Clinical Trial Registration numbers: 02570672, 04221750, 00620191, and 03733132. [R1]\n\n## Update\n\nLung Function After Randomization to Metformin, Lifestyle Intervention or Placebo in the Diabetes Prevention Program Outcome Study (DPPOS) reports: Conclusions: In this long-term follow-up after a randomized trial, there were no significant associations between randomization to metformin or lifestyle change and any measure of lung function measured 15 years after study completion. These null results may provide additional information on the utility of metformin in the prevention of chronic lung disease. [R2]\n\n## Synthesis\n\nTwo 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 inefficacy. [R1] [R2]\n\n## Limitations\n\nAssociation Between Metformin Use and Cognitive and Physical Function in Persons with HIV and Diabetes is observational with acknowledged small-sample and nonrandomized limitations, so it cannot establish causality. Lung Function After Randomization to Metformin, Lifestyle Intervention or Placebo in the Diabetes Prevention Program Outcome Study (DPPOS) is a conference-abstract record rather than a full peer-reviewed article, so its result is provisional. The receipts use different populations, comparators, endpoints, and designs; their estimates cannot be pooled, generalized, or treated as causal evidence for a uniform effect. [R1] [R2]\n\n## Falsifier\n\nFor Association Between Metformin Use and Cognitive and Physical Function in Persons with HIV and Diabetes, a preregistered randomized trial in Persons with HIV and Diabetes showing reproducible benefit on Cognitive Physical Function would overturn the first boundary. For Lung Function After Randomization to Metformin, Lifestyle Intervention or Placebo in the Diabetes Prevention Program Outcome Study (DPPOS), a full peer-reviewed randomized follow-up in the Diabetes Prevention Program Outcome Study (DPPOS) showing reproducible benefit on Lung Function would overturn the provisional second boundary.
