  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
Patients received care at tertiary care centers which could limit the generalizability of the findings. Patients and providers were aware of treatment assignment which could lead to assessment bias.
