Equivalence tests were originally used in areas such as pharmaceutics, frequently in bioequivalence trials. However, these tests can be applied to any instance where the research question asks whether the means of two sets of scores are practically or theoretically equivalent.
Bioequivalence is a term in pharmacokinetics used to assess the expected in vivo biological equivalence of two proprietary preparations of a drug. If two products are said to be bioequivalent it means that they would be expected to be, for all intents and purposes, the same.
Clinical trials testing potential medical products are commonly classified into four phases. The drug development process will normally proceed through all four phases over many years. [1] When expressed specifically, a clinical trial phase is capitalized both in name and Roman numeral, such as "Phase I" clinical trial. [1]
Randomized controlled trial [5]. Blind trial [6]; Non-blind trial [7]; Adaptive clinical trial [8]. Platform Trials; Nonrandomized trial (quasi-experiment) [9]. Interrupted time series design [10] (measures on a sample or a series of samples from the same population are obtained several times before and after a manipulated event or a naturally occurring event) - considered a type of quasi ...
Randomized clinical trials analyzed by the intention-to-treat (ITT) approach provide unbiased comparisons among the treatment groups. Intention to treat analyses are done to avoid the effects of crossover and dropout, which may break the random assignment to the treatment groups in a study.
[8] [9] Not all RCTs are randomized controlled trials (and some of them could never be, as in cases where controls would be impractical or unethical to use). The term randomized controlled clinical trial is an alternative term used in clinical research; [10] however, RCTs are also employed in other research areas, including many of the social ...
The FDA removed pages recommending the inclusion of more women and underrepresented groups in clinical trials, according to the lawsuit. Trump, a Republican, signed an executive order on his first ...
The main CONSORT Statement is based on the "standard" two-group parallel design. Extensions of the CONSORT Statement have been developed to give additional guidance for randomized trials with specific designs (e.g., cluster randomized trials, [3] noninferiority and equivalence trials, [4] pragmatic trials [5]), data (e.g., harms, [6] abstracts [7]), type of target outcome, [8] and various ...
