  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
The choice of Day 3 or Day 7 as randomization points while based on the literature were nevertheless somewhat arbitrary. cMR-baseed ejection fractions tended to be high.
