In response to overwhelming evidence and the consequences of poor-quality reporting of randomized, controlled trials (RCTs), many medical journals and editorial groups have now endorsed the CONSORT (Consolidated Standards of Reporting Trials) statement, a 22-item checklist and flow diagram. Because CONSORT primarily aimed at improving the quality of reporting of efficacy, only 1 checklist item specifically addressed the reporting of safety. Considerable evidence suggests that reporting of harms-related data from RCTs also needs improvement. ⋯ We hope that this document, in conjunction with other CONSORT-related materials (http://www.consort-statement.org), will help authors improve their reporting of harms-related data from RCTs. Better reporting will help readers critically appraise and interpret trial results. Journals can support this goal by revising Instructions to Authors so that they refer authors to this document.

The risk for atrial fibrillation-associated stroke increases at low anticoagulation intensities. However, higher intensities increase hemorrhage risk. Optimal use of warfarin for atrial fibrillation requires precise information on the risk for intracranial hemorrhage as a function of patient age and anticoagulation intensity. ⋯ The risk for intracranial hemorrhage increases at age 85 years. International normalized ratios less than 2.0 were not associated with lower risk for intracranial hemorrhage compared with INRs between 2.0 and 3.0. Therefore, anticoagulation management should focus on maintaining INRs in the 2.0 to 3.0 range, even in elderly patients with atrial fibrillation, rather than targeting INRs less than 2.0. Similarly, INRs of 3.5 or greater should be avoided.

Glucocorticoids have adverse systemic effects, including obesity, hypertension, and hyperglycemia, that may predispose to cardiovascular disease. The effect of glucocorticoid use on cardiovascular disease has not been quantified. ⋯ Treatment with high-dose glucocorticoids seemed to be associated with increased risk for cardiovascular disease.

Meta Analysis
Meta-analysis: angiotensin-receptor blockers in chronic heart failure and high-risk acute myocardial infarction.
The role of angiotensin-receptor blockers (ARBs) in treating patients with chronic heart failure and high-risk acute myocardial infarction (MI) has been controversial, and recent clinical trials provide more information on this topic. ⋯ Because ACE inhibitors and ARBs do not differ in efficacy for reducing all-cause mortality and heart failure hospitalizations in patients with chronic heart failure and in patients with high-risk acute MI, ARBs should be regarded as suitable alternatives to ACE inhibitors.

Randomized Controlled Trial Clinical Trial
Patient education for colon cancer screening: a randomized trial of a video mailed before a physical examination.
Colorectal cancer screening is underused, and primary care clinicians are challenged to provide patient education within the constraints of busy practices. ⋯ A mailed video had no effect on the overall rate of colorectal cancer screening and only modestly improved sigmoidoscopy screening rates among patients in primary care practices.
