SOURCE: Study-generated data.

NOTE: Most effective contraceptives: intrauterine devices or contraceptive implants. Moderately effective contraceptives: oral pill, patch, contraceptive injection, vaginal ring.

Adjusted means estimate (relative rate) of prevalence of contraception provision by Title X clinics vs non-Title X clinics, averaged across the entire study period, from a total of 4,608 clinic-quarters, 2016–2018. Estimates obtained from Poisson regression model with log link and autoregressive correlation structure with robust variance estimator; relative rate estimates from LSM estimate contrast statement of quarter*Title X interaction.
