Meta Analysis
Time to benefit for colorectal cancer screening: survival meta-analysis of flexible sigmoidoscopy trials.
To determine the time to benefit of using flexible sigmoidoscopy for colorectal cancer screening. ⋯ Our findings suggest that screening flexible sigmoidoscopy is most appropriate for older adults with a life expectancy greater than approximately 10 years.

Review Meta Analysis
Fruit and vegetable consumption and mortality from all causes, cardiovascular disease, and cancer: systematic review and dose-response meta-analysis of prospective cohort studies.
To examine and quantify the potential dose-response relation between fruit and vegetable consumption and risk of all cause, cardiovascular, and cancer mortality. ⋯ This meta-analysis provides further evidence that a higher consumption of fruit and vegetables is associated with a lower risk of all cause mortality, particularly cardiovascular mortality.

Meta Analysis
Revascularisation versus medical treatment in patients with stable coronary artery disease: network meta-analysis.
To investigate whether revascularisation improves prognosis compared with medical treatment among patients with stable coronary artery disease. ⋯ Among patients with stable coronary artery disease, coronary artery bypass grafting reduces the risk of death, myocardial infarction, and subsequent revascularisation compared with medical treatment. All stent based coronary revascularisation technologies reduce the need for revascularisation to a variable degree. Our results provide evidence for improved survival with new generation drug eluting stents but no other percutaneous revascularisation technology compared with medical treatment.
