Parameter	Beta coefficient	SE	95% CI	p	AOR	95% CI
Intercept	0.693	0.1961	0.309, 1.078	<0.001	2.00	1.36, 2.94
Couple group (Baseline DDS)	0.055	0.1427	−0.224, 0.335	0.698	1.06	0.799, 1.39
Women alone (Baseline DDS)	−0.268	0.1478	−0.557, 0.022	0.070	0.765	0.57, 1.02
Time	1.068	0.1474	0.779, 1.357	<0.001	2.91	2.18, 3.89
Couple group × time	0.838	0.1965	0.453, 1.223	<0.001	3.91	2.57, 6.88
Women alone × time	0.622	0.2139	0.202	0.001	2.86	2.17, 3.88

Note: The model was adjusted for maternal age, maternal education, maternal occupation, family size, wealth status, household food security status and baseline DDS. Group × time, intervention and time interaction. Maximum std. error = 0.214.

Abbreviations: AOR, adjusted odds ratio; CI, confidence interval; DDS, dietary diversity score; SE, standard error.
