  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Investigations indicate that the presence of metformin in future biomedical research (FBR) samples from non-rescued participants was due to participant self-administration of metformin outside of the protocol and without investigator knowledge.
