Note the nested nature of the table for the modern method category: the percentages for the pill, condoms, and injectables sum to the short-acting methods percentage while the percentages for the IUD and implants sum to the LARCs percentage. Similarly, the percentages for short-acting methods, LARCs, and permanent methods sum to the modern methods percentage.

↵a We opted not to present the adjusted DID point estimates with these associated P values because the adjusted estimates do not have an intuitive interpretation as the crude estimates do, which are the arithmetic difference-in-differences. Adjusted DID point estimates are available upon request.
