C, W, M, H: cells, worms or flies, mice, humans. Dark: independent labs found the same change there. Light: one lab or one study. Outline: nothing yet.

Labs are independent when their papers share no last author and no institution.

Against: findings that point the other way from most findings on the same outcome.

On aging: the drug’s trials ARN judged to be about aging, of every trial that tests it for any use.

No results posted: trials that ended more than a year ago with no results on ClinicalTrials.gov and no paper in ARN’s record.

Company ties: findings with an author at a company, or from a paper whose competing-interests statement declares ties to one.

Enhanced protein intake increases handgrip strength in humans (SMD 0.15, 95% CI 0.10 to 0.20).
“EPI was significantly associated with HGS (SMD: 0.15, 95% CI: 0.10 to 0.20; Z = 5.54, P < 0.0001; I2 = 6%, τ2 = 0.00) compared with the control group”
