Table 1.
Comparative reproductive parameters of users and non-users of (i) any method of contraception and (ii) artificial methods. CFS, completed family size; AFM, age at first marriage; AFB, age at first birth; ALB, age at last birth; fIBI, length of first inter-birth interval (months); RS, reproductive span (years); u5M, experience of under-five child mortality (yes or no). All comparisons are either Welch t-tests assuming unequal variances (continuous variables) or Fisher's exact tests (dichotomous variables).
