BACKGROUND AND OVERVIEW Dental practitioners spend most of their time administering treatments. To ensure that their clinical decisions are informed by the best available evidence, dental practitioners need to be skilled in critically appraising studies addressing therapy issues. Randomized controlled trials offer the optimal study design to inform decisions regarding therapy. The critical appr...
Recruitment and retention of participants in randomized controlled trials (RCTs) drawn from the older population is challenging, and studies have shown that poor recruitment and retention may lead to biased samples and results. Several strategies to improve the participation of older adults in research are outlined in the literature. The objective was to identify factors associated with partici...
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...
A novel strategy of discrete energy consumption model for WSN based on quasi Monte Carlo and crude Monte Carlo method is developed. In our model the discrete hidden Markov process plays a major role in analyzing the node location in heterogeneous media. In this energy consumption model we use both static and dynamic sensor nodes to monitor the optimized energy of all sensor nodes in which every...

I describe the findings of one of the largest randomized controlled trials (RCTs) of rehabilitation after traumatic brain injury (TBI) ever conducted, examine the theoretical relationship between cognitive and functional rehabilitation after TBI, and describe the historical preference for cognitive (top-down) rather than functional (bottom-up) interventions. I also contrast the goals and princi...
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...
PURPOSE OF REVIEW This review evaluated gender and race/ethnic representation in randomized controlled trials (RCTs) of patients with systemic lupus erythematosus (SLE). RECENT FINDINGS Whites comprise 33% of prevalent SLE cases and comprised 51% of RCT enrollees. Blacks encompass 43% of prevalent SLE cases, but only represented 14% of RCT enrollees. Hispanics comprise 16% of prevalent SLE ca...
Confinement of a plasma for controlled thermonuclear fusion is studied numerically. Toroidal equilibria are considered, with an emphasis on the Modular Helias-like Heliac 2 (MHH2), which is a stellarator of low aspect ratio with just two field periods surrounded by 16 modular coils. The geometry is fully three-dimensional, but there is an axial symmetry of the magnetic structure that is calcula...
