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
Prospectively defined outcome events, serious adverse events, adverse events leading to discontinuation, and investigator-determined drug-related adverse events were required for collection in this trial.
