A short cut review was carried out to establish whether the degree of rate control influences mortality in patients with atrial fibrillation. 22 papers presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these papers are shown in the two tables. It is concluded that there is insufficient evidence to recommend any specific rate control target to decrease mortality in rate-controlled rapid atrial fibrillation.

Sample size estimates are critical to the planning and interpretation of clinical studies, whether they are descriptive or analytical. Too small a sample size will result in imprecise estimates in a descriptive study and failure to achieve 'statistical significance' in an analytic or comparative study. Here we discuss what both researchers and readers should understand about the reasons for sample size estimates, how they are done and how achieving or not achieving the desired sample size can affect the interpretation of the outcomes.

Achieving just outcomes in sexual assault cases is one of the most serious and complex problems facing the healthcare and justice systems. This study was designed to determine the prevalence and correlates of Sexual Assault Evidence Kit (SAEK) completion and release to police among sexual assault cases presenting to the ED. ⋯ Even with access to specialised forensic evidence collection, many sexual assault survivors do not complete a SAEK, and even fewer release the evidence to police for investigation. The ED is a common entry points into the healthcare system, and this study has highlighted the need to strengthen services and reduce attrition along the health-justice continuum.
