Two null results cannot establish benefit beyond their measured settings. These receipts are paired only as an illustrative map of independent metformin findings on Cognitive Physical Function and Lung Function outcomes in distinct populations and organ systems; they are not pooled. Their different endpoints cannot be generalized into uniform efficacy or ine...

Across these trials, urolithin A improved multiple performance outcomes in middle-aged adults; in older adults, primary walk and ATP endpoints were null while muscle endurance improved. Because the cohorts and endpoints differed, this does not establish an age effect.
