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

Cognitive decline

downin humans1

1 study

Social activity participation decreases cognitive decline in humans.
“Notably, the interaction effect indicated that increasing social engagement over time may slow cognitive decline.”

Cognitive function

1 study

Social activity participation improves cognitive function in humans.
“Findings revealed that higher social activity participation predicted better cognitive function, with particularly beneficial effects observed in older age.”

Associations

Cognitive function

upin humans2

2 studies

Social activity participation is associated with cognitive function in humans (β = .127).
“Age was negatively associated with cognitive performance (β = -.089), while social activity participation was positively associated (β = .127).”

Perceived health

Perceived health is associated with social activity participation in humans (r=.18, p<.001).
“PH was positively correlated with SAP (r=.18, p<.001) and HA (r=.43, p<.001)”

Strength of the inverse age–cognition association

downin humans1

1 study

Social activity participation is associated with strength of the inverse age–cognition association in humans (Interaction β = .004, p < .05).
“A significant interaction (β = .004, p < .05) suggests that the strength of the age-cognition association varies by level of social engagement.”
