To the Editor, Boden and colleagues recent paper on the mental scars inflicted by the novel coronavirus and comparing it with the earlier coronavirus pandemics such as MERS and SARS is a major step in addressing the torn social fabric and the subsequent mental injury caused by the viral family [1] . The pandemic has led to a shadow mental health pandemic caused by our collective trauma. This study is valuable in furthering our understanding, regarding the magnitude and the wide impact of mental health issues caused by this pandemic.

Nonetheless, we are concerned about the methodology deployed by the authors that may dampen the robustness of this study. Boden and colleagues state that they planned on conducting a meta-regression, including a random summary effect, as implemented by a restricted likelihood method. In the actual study, however, they instead conduct a meta-regression including a dummy-coded disorder as a fixed effect moderator to obtain the summary prevalence of disorder across populations. Furthermore, in the protocol, the authors state that the profile plots indicated that all variance components were statistically identifiable. This difference in approach between stated methodology and implemented method requires clarification.

Additionally, in the protocol, the authors state that they were "estimating the mental health impact of COVID-19 on United States Populations", but in the final study, they estimated the prevalence in Canada, China, South Korea, Saudi Arabia, Singapore, Taiwan, Italy, Singapore, India and United States. This difference in stated objective and conducted analysis also requires to be clarified.
