Estimated with multivariate logistic regression with a binary outcome of an abortion occurring at or after 12 weeks’ gestation. Only abortions between March 15 and December 31 in 2019 and 2020 were included (n=14,436). The logistic model included terms for age group, time epoch (2020 vs 2019), and interaction terms between age group and time epoch. We also adjusted for race or ethnicity and insurance status. We excluded 7 abortions with missing values for insurance type for a final sample size of 14,339 abortions. We accounted for multiple abortions per person with generalized estimating equations using an exchangeable correlation structure.
