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.

1 study

Gamma radiation has no effect on chronic lymphocytic leukemia in humans.
“There was no evidence of external exposure effects on the risks of death from chronic lymphocytic leukemia, lymphoma, or multiple myeloma.”

1 study

Gamma radiation raises the risk of non-CLL leukemia in humans (ERR 2.45 at 1 Gy (95% CI 0.33 to 11.9)).
“While the largest ERRs [2.45 at 1 Gy, 95% confidence interval (CI) 0.33 to 11.9] were associated with external doses received between 2 and 5 years before death”
