Poor reporting of research hampers assessment and makes it less useful. An international group methodologists, researchers, journal editors sets out guidelines to improve reports observational studies
Many patients with severe aortic stenosis and coexisting conditions are not candidates for surgical replacement of the valve. Recently, transcatheter aortic-valve implantation (TAVI) has been suggested as a less invasive treatment high-risk stenosis.
The cardiovascular effect of liraglutide, a glucagon-like peptide 1 analogue, when added to standard care in patients with type 2 diabetes, remains unknown.In this double-blind trial, we randomly assigned diabetes and high risk receive liraglutide or placebo. primary composite outcome the time-to-event analysis was first occurrence death from causes, nonfatal myocardial infarction, stroke. hypothesis that would be noninferior placebo regard outcome, margin 1.30 for upper boundary 95%...
The use of transcatheter aortic-valve replacement has been shown to reduce mortality among high-risk patients with aortic stenosis who are not candidates for surgical replacement. However, the two procedures have compared in a randomized trial involving still

Among patients with aortic stenosis who are at intermediate or high risk for death surgery, major outcomes similar transcatheter aortic-valve replacement (TAVR) and surgical replacement. There is insufficient evidence regarding the comparison of two procedures in low risk.
Sodium–glucose cotransporter 2 (SGLT2) inhibitors reduce the risk of hospitalization for heart failure in patients regardless presence or absence diabetes. More evidence is needed regarding effects these drugs across broad spectrum failure, including those with a markedly reduced ejection fraction.
Sodium–glucose cotransporter 2 inhibitors reduce the risk of hospitalization for heart failure in patients with and a reduced ejection fraction, but their effects preserved fraction are uncertain.

Mineralocorticoid antagonists improve survival among patients with chronic, severe systolic heart failure and after myocardial infarction. We evaluated the effects of eplerenone in chronic mild symptoms.

In controlled clinical trials there are usually several prognostic factors known or thought to influence the patient's ability respond treatment. Therefore, method of sequential treatment assignment needs be designed so that balance is simultaneously achieved across all such patients factor. Traditional methods restricted randomization as "permuted blocks within strata" prove inadequate once number strata, combinations factor levels, approaches sample size. A new general procedure for...
The CONSORT (Consolidated Standards of Reporting Trials) Statement, which includes a checklist and flow diagram, is guideline developed to help authors improve the reporting findings from randomized controlled trials. It was updated most recently in 2010. Its primary focus on individually trials with 2 parallel groups that assess possible superiority one treatment compared another. Statement has been extended other trial designs such as cluster randomization, recommendations for...

Iron deficiency may impair aerobic performance. This study aimed to determine whether treatment with intravenous iron (ferric carboxymaltose) would improve symptoms in patients who had heart failure, reduced left ventricular ejection fraction, and deficiency, either or without anemia.
Treatment with the direct thrombin inhibitor bivalirudin, as compared heparin plus glycoprotein IIb/IIIa inhibitors, results in similar suppression of ischemia while reducing hemorrhagic complications patients stable angina and non-ST-segment elevation acute coronary syndromes who are undergoing percutaneous intervention (PCI).

Antithrombotic drugs are used after coronary-artery stenting to prevent stent thrombosis. We compared the efficacy and safety of three antithrombotic-drug regimens — aspirin alone, warfarin, ticlopidine coronary stenting.
In clinical trials with sequential patient entry, fixed sample size designs are unjustified on ethical grounds and often impracticable. One solution is a group design dividing entry into number of equal-sized groups so that the decision to stop trial or continue based repeated significance tests accumulated data after each evaluated. Exact results obtained for two treatments normal response known variance. The problem determining required also considered. Simulation shows these may be...
