Abbreviations: CI, confidence interval; FABM, fertility awareness-based method; SDM, Standard Days Method.
↵a Incorporating information on multiple method use. This approach assumes that women in Categories A and B in Table 2 rely primarily on an FABM and may routinely or occasionally use condoms and/or EC during days they believe to be fertile.
↵b The “either” category does not always equal the sum of the “rhythm” and “SDM” category due to a small number of women who reported both methods.
