Intention To Treat Analysis: From 1 Different Sources


a research process in which results are reported according to the treatment arm to which a research subject was assigned, rather than the treatment eventually received. Intention to treat analysis is very widely used in clinical research as a method of avoiding *bias resulting from nonrandom withdrawal from the trial or crossover between treatment arms.

Meta-analysis

A statistical procedure to combine results from different studies on a similar topic. The combination of results from multiple studies may produce a stronger conclusion than can be provided by any singular study. Meta-analysis is generally most appropriate when there are no definitive studies on a topic and non-definitive studies are in some disagreement.... meta-analysis

Analysis

Analysis means a separation into component parts by determination of the chemical constituents of a substance. The process of analysis is carried out by various means, for example: chromatographic analysis by means of the adsorption column; colorimetric analysis by means of various colour tests; densimetric analysis by estimation of the speci?c gravity; gasometric analysis by estimation of the di?erent gases given o? in some process; polariscope analysis by means of the polariscope; and volumetric analysis by measuring volumes of liquids. Analysis is also sometimes used as an abbreviation for PSYCHOANALYSIS.... analysis

Cost-benefit Analysis

The systematic comparison, in monetary terms, of all the costs and benefits of proposed alternative schemes with a view to determining: which scheme or combination of schemes will contribute most to the achievement of predetermined objectives at a fixed level of investment; or the magnitude of the benefit that can result from schemes requiring the minimum investment. The resources required per unit of benefit must be determined, account being taken of the fact that costs and benefits accrue with time. For example, the cost of establishing a home and community care programme might be compared with the total cost of building residential facilities. Cost-benefit analysis can also be applied to specific medical tests and treatments.... cost-benefit analysis

Decision Analysis

An approach to decision-making that involves modelling the sequences or pathways of multiple possible strategies (e.g. of diagnosis and treatment for a particular clinical problem) to determine which is optimal. It is based upon available estimates (drawn from the literature or from experts) of the probabilities that certain events and outcomes will occur and the values of the outcomes that would result from each strategy.... decision analysis

Jungian Analysis

A school of ‘analytical psychology’, ?rst described by Carl Gustav Jung in 1913. It introduced the concepts of ‘introvert’ and ‘extrovert’ personalities, and developed the theory of the ‘collective unconscious’ with its archetypes of man’s basic psychic nature. In contrast with Freudian analysis (see FREUDIAN THEORY), in Jungian analysis the relationship between therapist and patient is less one-sided because the therapist is more willing to be active and to reveal information about him or herself. (See also PSYCHOANALYSIS.)... jungian analysis

Hair Analysis

Hair is believed to be a “time capsule” of a person’s metabolic activity. Believed to be a useful means of acquiring information regarding the concentration of mineral nutrients and toxins. Alone, it does not provide sufficient evidence for purposes of diagnosis, but helpful in building a picture of the nutritional state of the patient. ... hair analysis

What Causes Ear Tinnitus And How To Treat It

Tinnitus in the ear can occur due to ear infections, various infections, perforation of the eardrum, and many other effects. This is a condition that one should especially take seriously. At the same time, tinnitus can also occur in the formation of brain tumors and as a result of an impact on the person. After experiencing these conditions, it is necessary to consult a physician in order to avoid ringing of the ear which has started to occur. If your tinnitus does not seem to be a symptom of a serious illness, and if it is coming up in a short period of time, you can apply the recommendation we will give you. What do you need to do to treat and prevent tinnitus? - regular exercise every day - As far as possible you should stay away from bike and horse riding sports. - Eating a bottle of mineral water every day is a good night to tinnitus. - Avoiding loud surroundings will protect you from the tinnitus problem. - Coffee cigarettes Alcohol and caffeine containing foods should be avoided. - If you have a drug that you use all the time, you should investigate whether the drugs you use trigger the tinnitus. If you think your tinnitus is caused by medications you are using, you can ask your doctor to change the medications. - Consuming one pineapple every day will greatly reduce your tinnitus... what causes ear tinnitus and how to treat it

Analysis, Chemical

Determination of the identity of a substance or of the individual chemical constituents of a mixture. Analysis may be qualitative, as in determining whether a particular substance is present, or it may be quantitative, that is, measuring the amount or concentration of one or more constituents. (See also assay.)... analysis, chemical

Chromosome Analysis

Study of the chromosomes in body cells to discover whether a chromosomal abnormality is present or to establish its nature. Fetal cells for analysis can be obtained in the uterus by amniocentesis or chorionic villus sampling. If a serious abnormality such as Down’s syndrome is identified, termination of the pregnancy and genetic counselling is offered. Chromosome analysis is also carried out when a baby is stillborn without an obvious cause, or is born with abnormal physical characteristics that suggest a chromosomal defect, such as Turner’s sydrome.

Chromosome analysis in children and adults uses white blood cells taken from a blood sample. Analysis of the sex chromosomes may be carried out to establish the chromosomal sex of a child in cases where the genitals have an ambiguous appearance (see genitalia, ambiguous); to confirm or exclude the diagnosis of chromosomal abnormalities; or to investigate infertility.... chromosome analysis

Dream Analysis

The interpretation of a person’s dreams as part of psychoanalysis or psychotherapy.

First developed by Sigmund Freud, it is based on the idea that repressed feelings and thoughts are revealed, in a disguised manner, in dreams.... dream analysis

It is used to investigate male infertility and is also done some weeks after vasectomy to ensure that the semen no longer contains sperm.... seminal fluid analysis

First Intention

see intention.... first intention

Intention

n. 1. a process of healing. Healing by first intention is the natural healing of a wound or surgical incision when the edges are brought together under aseptic conditions and *granulation tissue forms. In healing by second intention the wound edges are separated and the cavity is filled with granulation tissue over which epithelial tissue grows from the wound edges. In healing by third intention the wound ulcerates, granulations are slow to form, and a scar forms at the wound site. 2. evaluation of a person’s aims or purpose in undergoing an action, which is important for the assessment and attribution of responsibility in ethicolegal questions and defined legally for the purposes of criminal law. See also doctrine of double effect.... intention

Intention Tremor

Seminal Analysis

analysis of a specimen of semen, which should be obtained after five days of abstinence from coitus, in order to assess male fertility. Normal values are as follows: volume of ejaculate: 2–6.5 ml; liquefaction complete in 30 minutes; sperm concentration: 20–200 million spermatozoa per ml (sperm count refers to the total number of spermatozoa in the ejaculate); motility: 60% moving progressively at 30 minutes to 3 hours; abnormal forms: less than 20%. Analysis of three separate specimens is necessary before confirming the presence of an abnormal result.... seminal analysis

Six-category Intervention Analysis

a framework for exploring how care is delivered, based on the idea that there are six main styles of interaction (prescriptive, informative, confronting, cathartic, catalytic, and supportive). The analysis is widely used to help health-care professionals develop an understanding of interpersonal relationships, reflect on their own practice, and enhance their interactions with clients.... six-category intervention analysis

Southern Blot Analysis

a technique for identifying a specific form of DNA in cells. The DNA is extracted from the cells and restriction enzymes used to cut it into small fragments.

Southern (1938– ), US biologist]... southern blot analysis
