Study population: The group of people participating in a clinical research study discount accutane 10 mg fast delivery skin care nz. The study population often includes people with a particular problem or disease 5 mg accutane visa acne types. It may also include people who have no known diseases. Subgroup analysis: An analysis in which an intervention is evaluated in a defined subset of the participants in a trial, such as all females or adults older than 65 years. Superiority trial: A trial designed to test whether one intervention is superior to another. Surrogate outcome: Outcome measures that are not of direct practical importance but are believed to reflect outcomes that are important; for example, blood pressure is not directly important to patients but it is often used as an outcome in clinical trials because it is a risk factor for stroke and heart attacks. Surrogate endpoints are often physiological or biochemical markers that can be relatively quickly and easily measured, and that are taken as being predictive of important clinical outcomes. They are often used when observation of clinical outcomes requires long follow-up. Drugs for fibromyalgia 66 of 86 Final Original Report Drug Effectiveness Review Project Survival analysis: Analysis of data that correspond to the time from a well-defined time origin until the occurrence of some particular event or end-point; same as time-to-event analysis. Systematic review: A review of a clearly formulated question that uses systematic and explicit methods to identify, select, and critically appraise relevant research and to collect and analyze data from the studies that are included in the review. The extent to which a drug’s adverse effects impact the patient’s ability or willingness to continue taking the drug as prescribed. These adverse effects are often referred to as nuisance side effects, because they are generally considered to not have long-term effects but can seriously impact compliance and adherence to a medication regimen. Treatment regimen: The magnitude of effect of a treatment versus no treatment or placebo; similar to “effect size”. Can be calculated in terms of relative risk (or risk ratio), odds ratio, or risk difference. Two-tailed test (two-sided test): A hypothesis test in which the values that reject the null hypothesis are located in both tails of the probability distribution. For example, testing whether one treatment is different than another (rather than testing whether one treatment is either better than another). Type I error: A conclusion that there is evidence that a treatment works, when it actually does not work (false-positive). Type II error: A conclusion that there is no evidence that a treatment works, when it actually does work (false-negative). Validity: The degree to which a result (of a measurement or study) is likely to be true and free of bias (systematic errors). Variable: A measurable attribute that varies over time or between individuals. Variables can be • Discrete: taking values from a finite set of possible values (e. Washout period: [In a cross-over trial] The stage after the first treatment is withdrawn, but before the second treatment is started. The washout period aims to allow time for any active effects of the first treatment to wear off before the new one gets started.
