The motivation to engage students has been a challenge in teaching and learning statistics. This study investigates the effectiveness of online peer learning in enhancing students’ academic achievement and promoting their motivation. The researcher employed a quasi-nonequivalent (preand posttest) control group design to investigate the effectiveness of online peer learning. The participants in ...

To appraise the current reporting methodological quality of randomized clinical trials (RCTs) in 3 leading diabetes journals.We systematically searched the literature for RCTs in Diabetes Care, Diabetes and Diabetologia from 2011 to 2013.Characteristics were extracted based on Consolidated Standards of Reporting Trials (CONSORT) statement. Generation of allocation, concealment of allocation, in...

Clinical trials constitute one of the main sources of medical knowledge, yet trial reports are difficult to find, read, and apply to clinical care. Reasons for these difficulties include the lack of a common, standardized, structure for trial reports; the restricted length of reports; and limited computer support for use of the literature. We propose a new model of reporting clinical trials, in...

Randomized clinical trials of new coronary devices, as with other novel therapies, are generally conducted in a homogeneous and usually low-risk population. There is valid statistical and methodological justification for this approach, including lower variances (resulting in increased statistical power) and increased probability that observed differences are due only to the study therapy. Altho...

A relatively high burden of influenza is experienced by young children. In order to successfully tackle the burden of influenza in children, effective vaccines are necessary. Accumulated evidence on the efficacy and effectiveness of traditional inactivated split or subunit trivalent influenza vaccines points towards no significant protection in the youngest children, who are largely unprimed. A...

Reports in the scientific and lay press on the current evidence from epidemiological and clinical trials for the benefit of lowering blood cholesterol often appear to be at variance. In May 1993 the British Hyperlipidaemia Association held a symposium at the Royal College of Physicians' to establish where there was agreement and to produce guidelines to identify people who might live longer as ...

Clinical trials have been the main tool used by the health sciences community to test and evaluate interventions, Trials can fall into two broad categories: pragmatic and explanatory. Pragmatic trials are designed to evaluate the effectiveness of interventions in real-life routine practice conditions, whereas explanatory trials aim to test whether an intervention works under optimal situations....

BACKGROUND Evidence-based medicine has been advanced by the use of standards for reporting the design and methodology of randomized controlled trials (RCT). Indeed, without this information it is difficult to assess the quality of evidence from an RCT. Although a variety of statistical methods are available for the analysis of recurrent events, reporting the effect of an intervention on outcome...

BACKGROUND AND PURPOSE The methodological quality of randomized controlled trials (RCTs) is commonly evaluated in order to assess the risk of biased estimates of treatment effects. The purpose of this systematic review was to identify scales used to evaluate the methodological quality of RCTs in health care research and summarize the content, construction, development, and psychometric properti...

T HE RANDOMIZED CLINICAL TRIAL IS THE GOLD standard for evaluating a therapy, providing the highest evidence for the practice of evidence-based medicine. However, not all randomized clinical trials are informative and the success of the trial in demonstrating a valid treatment or diagnostic effect will depend on the elements of the study design. The purpose of this report is to highlight the es...
