  Ginger Supplementation and Blood Pressure in Adults: A GRADE-Based Systematic Review and Dose-Response Meta-Analysis of Randomized Controlled Trials

  Pooling 12 randomised trials, ginger supplementation was associated with a 5.03 mmHg drop in systolic and a 2.03 mmHg drop in diastolic blood pressure, with larger reductions in trials that used 2000 mg a day or more. The authors rate the certainty of their own evidence as low, because the trials disagree with each other.

  Pooling 26 crossover trials in female team sport athletes, caffeine produced a small edge in sprinting, jumping and change of direction, and made hard efforts feel easier. Skill based and cognitive outcomes showed nothing reliable, and no dose, timing or format pattern held up.

  The effects of oral antioxidants on outcomes of assisted reproductive technology: a systematic review and meta-analysis of randomized controlled trials

  Pooling 14 randomised trials of oral antioxidants in IVF and ICSI, researchers found higher clinical pregnancy rates and more mature eggs collected. The live birth signal came from just three trials and disappeared when one of them was removed.

  Across one hundred and sixty seven trials, the size of the energy cut predicted the weight loss and the meal timing did not

  Three degrees of ordinary calorie cutting and four kinds of fasting, compared at matched absolute energy restriction across 167 trials and nearly twelve thousand people. The ranking came out by how much energy each regimen removed. The authors state the conclusion as a negative.

  Against ordinary dietary advice, twenty two trials of intermittent fasting moved weight by a third of one percent

  The first Cochrane review of intermittent fasting split the question in two. Against regular dietary advice the difference in weight was minus 0.33 percent and the interval crossed zero. Against no intervention at all it was minus 3.42 percent. Same review, same trials, two comparators.
