Estimated effect of the Comprehensive Rural Health Project (CRPH) on under-5 child mortality, Maharashtra state, India, September 1992–December 2007a Model HR 95% CI Under 5 yrb Crude 0.93 0.77–1.11 Controlled for caste +religion + irrigation 0.90 0.75–1.09 Controlled for caste + religion + irrigation + birth period 0.91 0.75–1.09 Neonatalc Crude 1.06 0.84–1.33 Controlled for caste + religion + irrigation 1.03 0.82–1.29 Controlled for caste + religion + irrigation + birth period 1.04 0.83–1.31 Post-neonatal but under 5 yrc Crude 0.72 0.54–0.96 Controlled for caste + religion + irrigation 0.70 0.52–0.94 Controlled for caste + religion + irrigation + birth period 0.70 0.52–0.95 CI, confidence interval; HR, hazard ratio. a There were 10 883 children. Age at death was missing for 2 children and caste was missing for 11 children. Children with missing data were excluded from the models. b “Under 5 yr” was estimated from the model without interaction between age bands and CRHP intervention. c “Neonatal” and “post-neonatal but under 5 yr” were estimated from the model including interaction between age bands and CRHP intervention.
