Table 5 Secondary outcomes of the eRegMat cluster-randomized controlled trial

Outcome	Control group^a	Intervention group^a	Adj. RR	95% Interval^b		p	ICC^c
Timely first ANC visit^d	188/348 (54.0%)	252/445 (56.6%)	0.97	[0.84	1.11]	0.639	0.014
High risk women referred^e	3/13 (23.1%)	2/10 (20.0%)	1.27	[0.27	5.96]	0.765	0.000
Facility delivery^d	61/77 (79.2%)	93/124 (75.0%)	0.95	[0.82	1.11]	0.532	0.000
Mortality and morbidity (all women)^d	131/874 (15.0%)	136/934 (14.6%)	0.74	[0.58	0.96]	0.021	0.038
Mortality and morbidity (women with risk factors)^e	11/55 (20.0%)	8/75 (10.7%)	0.49	[0.23	1.09]	0.079	0.096
Severe postpartum anemia^e	0/81 (0.0%)	1/68 (1.5%)	6.31	[0.09	31.20]	N/A

^aData are n/N (%), aggregate over visit and clinic, and exclude women with missing outcome data. Numerators and denominators exclude pregnant women in the intervention arm who were not exposed to the intervention and exclude pregnant women in the control arm who could not have been exposed to the intervention; had they instead been randomized to the intervention arm
^bPrecision is quantified using 95% confidence intervals for all outcomes except those for which Bayesian estimation was performed (indicated by N/A in the p-value column); precision is quantified for those outcomes using 95% equal-tailed credible intervals
^cIntraclass correlation coefficients were estimated using mixed effects logistic regression
^dAdjusted for the variables used for stratified and restricted randomization
^eAdjusted for clustering within clinic and repeated antenatal care visits (where applicable). All randomized pregnant women with outcome data are included and analyzed in the arms to which their clinics were randomized
