In contrast, pragmatic trials attempt to understand the real-world benefit of an intervention by incorporating design elements that allow for greater generalizability and clinical applicability of study results. Objective Phase IV trials are often used to investigate drug safety after approval. 1 Clinical Trials in Rare Diseases: Challenges in Design, Analysis, and Interpretation Michael P. McDermott, Ph.D. University of Rochester Medical Center How are trials set up? From significance testing to P values and intention-to-treat analyses, Dr Stuart Pocock reviews the basics of clinical trial interpretation.

Objectives Interpretation of CIs in randomised clinical trials (RCTs) with treatment effects that are not statistically significant can distinguish between results that are ‘negative’ (the data are not consistent with a clinically meaningful treatment effect) or ‘inconclusive’ (the data remain consistent with the possibility of a clinically meaningful treatment effect).

Clinical trials are experiments designed to evaluate new interventions to prevent or treat disease in humans. This could have implications for the design and interpretation of clinical trials, for example, incorporating longer-term surveillance of trial participants and accounting for duration of treatment effect in risk-benefit assessments. Clinical trials are useful for demonstrating efficacy and safety of various medical therapies, preventative measures and diagnostic procedures if the treatment can be applied uniformly and potential biases controlled. Part A subdivision of a single protocol into major building blocks. This paper concentrates on problems relating to randomisation, the overemphasis on significance testing, and the inadequate size of many trials.

In Experimental studies, researchers assign patients to an experimental or control group. Indeed, well-designed and rigorously conducted trials can establish the etiologic relevance of modifiable risk factors and the benefits (and risks) of candidate therapies.
