文摘

The authors reviewed approaches for assessing echocardiographic reproducibility in research. Statistical methods assessing echocardiographic data quality vary substantially. For each echocardiographic variable (such as LV ejection fraction), the range of values for each statistical metric is large. The relative data quality varies depending on the metric examined. Achievable precision metrics were identified for each echocardiographic variable (such as LV ejection fraction) in the studies examined.
