Fig. 3: Long COVID, risk in different sub-populations in PCORnet and N3C cohorts.
From: Long COVID after SARS-CoV-2 during pregnancy in the United States
Corresponding sub-populations in the SARS-CoV-2 infected pregnant women and the infected non-pregnant women were compared. Outcomes were ascertained 30 days after the first documented SARS-CoV-2 infection evidence until the end of the follow-up. The absolute risk, risk ratio, and risk difference were captured by the cumulative incidence (CIF), hazard ratio (HR), and the difference of cumulative incidence per 100 persons (DIFF/100), estimated at 180 days after the infection index date, respectively. The centers of the error bars were adjusted hazard ratios calculated by the Cox proportional hazard model, and error bars indicated two-sided 95% confidence intervals (95% CI). Having co-existing risk factors is having any hypertension, diabetes, class III obesity, and asthma at baseline.
