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.

Outcomes

Recall

upin humans1

1 study

Health insurance improves recall in humans (MHAS β=0.110, p <0.01; HRS β=0.274, p <0.01).
“Having government health insurance vs those without predicted better immediate recall in MHAS (β=0.110, p <0.01), and improved delayed recall in HRS (β=0.274, p <0.01).”

“DunedinPoAm (Insured: β = 0.001, 95% CI: -0.002, 0.003; Uninsured β = 0.01, 95% CI 0.0001, 0.02; P interaction = 0.047)”
