Someone can correct me, but is this paper really making the claim that wearing masks a contributing factor to stillbirth rates in Asia? >Other cultures have been wearing face masks long before COVID [[157]]. The prepandemic face mask wearing habits of such countries are not comparable to the pandemic face mask wearing requirements, but scientific data supports our hypotheses from sections 4.1. and. 4.2. Even before the pandemic, in Asia the stillbirth rates have been significantly higher compared to e.g. Eurasia, Oceania or North Africa Also, the authors don't explain how pre-pandemic mask wearing is different than pandemic mask wearing.
