What type of study design for clinical research ?
Advantages Disadvantages Phase III randomized trial (non-inferiority) - Conclusion based on statistical results - Scientific impact (no previously reported study) - Clinical and statistical impact - Multicentric - Huge number of enrolled patient - Cost - Duration of the study - Uncertainty of the final results at the end of the study Phase 2 randomized trial (According to a Fleming one step statistical design) - Reasonable # of enrolled pt - Possible switch to phase III - No statistical comparison Retrospective study based on a matched-pair analysis - Duration: immediate results - Statistical comparison - Can be perform concomitantly with a prospective study - Retrospective analysis - No consistent conclusion in terms of clinical research Observatory study - No calculation of a needed number of enrolled patient - Quick conclusion - Non rigorous study - Low scientific impact - No consistent conclusion
