UNLABELLED The present study used a randomized clinical trial design to examine the effectiveness of personalized alcohol feedback delivered individually, in a group and via computer on alcohol use and related negative consequences in a sample of 173 college students referred for alcohol-related violations. Findings revealed statistically significant reductions in alcohol use and related harms ...
BACKGROUND AND AIMS The Cochrane Hepato-Biliary Group (CHBG) is one of the 52 collaborative review groups within The Cochrane Collaboration. The activities of the CHBG focus on collecting hepato-biliary randomized clinical trials (RCT) and controlled clinical trials (CCT), and including them in systematic reviews with meta-analyses of the trials. In this overview, we present the growth of The C...
Since there remains a need to examine the nature of the neural effect and therapeutic efficacy/effectiveness of sensory stimulation provided to persons in states of seriously impaired consciousness, a passive sensory stimulation intervention, referred to as the Familiar Auditory Sensory Training (FAST) protocol, was developed for examination in an ongoing, double-blind, randomized clinical tria...
Bringing evidence-based treatments to community practice is a critical challenge for the field. When implemented in the community, evidence-based treatments often fail to provide the benefits shown in laboratory settings. Therefore, when evidence-based treatments are transported to the community, it is essential to investigate implementation process and outcomes. The present study assessed whet...
A major challenge in the development of anticancer therapies is the considerable time and resources needed for conducting randomized clinical trials (RCT). There is a need for more efficient RCT designs that accelerate development, minimize costs, and make trials more appealing to patients. We review the statistical and logistical characteristics of multi-arm designs that compare several experi...
Events of the past decade or so argue that there is little support in the literature for much of the specialty's treatment portfolio. The resulting call for 'evidence-based' treatment (not to mention the obvious intellectual bankruptcy of much of the clinical literature) has prompted many to argue that the randomized clinical trial (RCT) represents the future of orthodontic clinical investigati...
OBJECTIVE Considering the importance of randomized clinical trials (RCTs) in the evidence-based approach, the objective of this study was critical appraisal of reporting RCTs in Iranian dental journals. MATERIALS AND METHODS After adequate searching, 113 RCT articles published during 2003-2010 were reviewed for quality of reporting with the CONSORT scale. The quality of each paper was assesse...
As randomized clinical trial (RCT) programs have increasingly become more global geographically, numerous challenges have resulted. One issue that arises with such global programs is the sometimes differing regulatory advice or requirements on primary or secondary endpoints. The International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use...
Randomized clinical trials (RCTs) not only are the gold standard for evaluating the efficacy and effectiveness of psychiatric treatments but also can be valuable in revealing moderators and mediators of therapeutic change. Conceptually, moderators identify on whom and under what circumstances treatments have different effects. Mediators identify why and how treatments have effects. We describe ...
This paper is a practical guide to the essentials of statistical analysis and reporting of randomized clinical trials (RCTs). It is the first in a series of 4 educational papers on statistical issues for RCTs, which will also include statistical controversies in RCT reporting and interpretation, the fundamentals of design for RCTs, and statistical challenges in the design and monitoring of RCTs...
