The study authors used different sources of outcomes data for the intervention and comparison groups, and they used specific imputation approaches for each data source. This approach creates a confounding factor because observed effects could be attributed to the manner of data collection rather than the effectiveness of the intervention condition. HomVEE standards require a consistent manner of data collection between the intervention and comparison conditions and that the imputation approach be the same in each group.
