Equivalence Trial - ANSWER A trial with the primary objective of showing that the response to two or more treatments differs by an amount which is clinically unimportant. This is usually demonstrated by showing that the true treatment difference is likely to lie between a lower and an upper equivalence margin of clinically acceptable differences. Generalisability - ANSWER The extent to which results can be generalised beyond the sample to a wider population or situation Global Assessment Variable - ANSWER A single variable, usually a scale of ordered categorical ratings, which integrates objective variables and the investigator's overall impression about the state or change in state of a subject.

Surrogate variable - ANSWER A variable that provides an indirect measurement of effect in situations where direct measurement of clinical effect is not feasible or practical. factorial design - ANSWER a study in which there are two or more independent variables, or factors primary variable - ANSWER -the variable capable of providing the most clinically relevant and convincing evidence directly related to the objective -should only be one secondary variable - ANSWER not part of the hypothesis under investigation but have potential for confounding study endpoint - ANSWER Occurrence of a disease, symptom, or sign that constitutes one of the target outcomes of the trial, but may also refer to any such disease or sign that strongly motivates the withdrawal of that individual from the trial (humane endpoint). phase 1 study - ANSWER a pilot study of a potential drug done with a small number of
