When compared to control in mITT DiD models, the ARCHES intervention group demonstrated a marginally significant increase in covert contraceptive use from baseline to three-month follow-up but not baseline to six-month follow-up (mITT baseline to three-month follow-up beta 0.77; 95% CI −0.09,1.63; p = 0.08, baseline to six-month follow-up beta 0.38; 95% CI −0.92, 1.69; p = 0.57, Table 3 ).
