Table 3. Mean scores in key variables at baseline and follow-up in control and intervention arms, the cluster randomized trial to increase iron and folic acid consumption in Odisha, India, September 2019–February 2020.

Variable	Control arm				Intervention arm				P a
	Mean (SD)		P		Mean (SD)		P
	Baseline (n = 2048)	Follow-up (n = 1966)			Baseline (n = 2060)	Follow-up (n = 1987)
Descriptive norms	1.08 (0.62)	1.23 (0.62)	< 0.001		1.07 (0.60)	2.06 (0.67)	< 0.001		< 0.001
Injunctive norms	2.66 (0.74)	2.92 (0.75)	< 0.001		2.55 (0.74)	3.60 (0.59)	< 0.001		< 0.001
Collective norms	0.39 (0.32)	0.30 (0.24)	< 0.001		0.39 (0.26)	1.57 (0.87)	< 0.001		< 0.001
Iron and folic acid consumption	0.39 (1.90)	0.31 (1.57)	NS		0.39 (1.92)	1.62 (3.17)	< 0.001		< 0.001

NS: not significant; SD: standard deviation.

^a Compares differences in key variables from baseline to follow-up in the control arm with differences in the same variables in the intervention arm.

Note: For all variables, higher scores signify greater iron and folic acid consumption (and supportive norms for this consumption).
