Following publication of this Article concerns have been raised about the methodological approach developed by the Authors to evaluate the impact of stay-at-home policies on the reduction of COVID-19-related fatalities. In particular, Meyerowitz-Katz et al.[1] show that the approach fails to detect any signal when tested on a synthetic dataset where the ground truth is known, and under specific cases of data subsetting. In addition, Meyerowitz-Katz et al.[1] failed to replicate the original results using a synthetic dataset. These suggest that the false negative rate of the approach is prohibitively high to allow for meaningful conclusions to be drawn regarding the impact of stay-at-home policies on COVID-19 fatality rates. The results of Meyerowitz-Katz et al.[1] are further confirmed by Góes[2] who, using a pure correlation analysis, shows that the coefficients for the impact of stay-at-home policies using the methodological approach developed by the Authors can be zero even with diametrically opposing indices of staying-at-home. Given these concerns, the Editors no longer have confidence that the conclusions presented are adequately supported.
