Randomized Controlled Trial
Effects of calcium supplementation on body weight and adiposity in overweight and obese adults: a randomized trial.
Some data suggest that increasing calcium intake may help prevent weight gain. ⋯ Dietary supplementation with elemental calcium, 1500 mg/d, for 2 years had no statistically or clinically significant effects on weight in overweight and obese adults. Calcium supplementation is unlikely to have clinically significant efficacy as a preventive measure against weight gain in such patients.

Randomized Controlled Trial Multicenter Study
Stent placement in patients with atherosclerotic renal artery stenosis and impaired renal function: a randomized trial.
Little is known about the efficacy and safety of renal artery stenting in patients with atherosclerotic renal artery stenosis (ARAS) and impaired renal function. ⋯ Stent placement with medical treatment had no clear effect on progression of impaired renal function but led to a small number of significant procedure-related complications. The study findings favor a conservative approach to patients with ARAS, focused on cardiovascular risk factor management and avoiding stenting.
