Table 2 Matching socio-demographic characteristics of SHG women who were not exposed to health intervention with those who were exposed, Bihar, India, 2016

Women who belong to self-help groups
Socio-demographic characteristics	Exposed to health intervention	Matched unexposed	p-value ^d
Mean age in years (SD)	27.5 (4.6)	27.4 (4.4)	0.917
Had 3 or more children	77.4	77.9	0.831
Belongs to SC/ST ^a	91.6	90.6	0.540
Formal schooling ^b	17.9	18.6	0.771
SHG women engaged in some occupation	43.7	40.1	0.212
Duration of association with SHG
Less than equal to 12 months	3.5	3.7	0.896
13–24 months	19.3	19.3	0.992
25 or more months	77.2	77.0	0.947
N ^c	597	598
Likelihood ratio χ2 test statistic (p value) ^e
Before matching	210.69 (< 0.001)
After matching	2.01 (0.959)

SD standard deviation
*p < 0.10; **p < 0.05; ***p < 0.01
^a SC-Scheduled Caste, ST-Scheduled Tribe
^b Formal schooling refers to the ability to both read and write
^c Differences in N values for matched unexposed and unexposed is the number of unexposed cases dropped from the analysis as no match could be found for them
^d p values were obtained by comparing percentages for those who were exposed to health intervention and matched unexposed SHG women. Matched unexposed refers to SHG women who were unexposed to health intervention and had propensity scores similar to that for those exposed SHG women. Differences in percentages were tested using χ² test statistics and differences in average values were tested using unpaired t statistic
^e The likelihood ratio χ² test statistic was used to test the joint significance of all the regressors before and after matching
