Abstract

Authors´ conclusions: there was no special variation regarding premature birth (<37 weeks) or stillbirth (fetal demise as of 20 weeks of gestational age) rates over the first 12 months of the SARS-CoV-2 pandemic, beyond the natural variation observed over the 17.5 years before the pandemic started.

Reviewers´ commentary: this is a retrospective cohort study run in Ontario (Canada). The statistical techniques employed (control charts, interrupted time series analysis) and its population-based nature make the present study one of the soundest studies on the topic from a methodological point of view. However, its geographic restriction hampers the generalization of the study´s results to other areas where the pandemic or the Health System´s characteristics might have been different.
