Table 2 Unadjusted Regressions

From: An ecological quantification of the relationships between water, sanitation and infant, child, and maternal mortality

  Coefficient (95% Confidence interval (CI)) p-value
Predictor: proportion of population with access to improved water source a
   Under-five mortality rate (per 1 000 live births) -2.25 (-2.50,-2.05)b < 0·001
   % under-five mortality due to diarrheaa OR:0·20 (0·14, 0·28)c < 0·001
   IMR (per 1 000 live births) -2.12 (-2.29,-1.93) < 0·001
   MMRb (per 100 000 live births) OR:0·20 (0·14, 0·28) < 0·001
Predictor: proportion of population with access to improved sanitation a
   Under-five mortality rate (per 1 000 live births) -2.45 (-2.66,-2.27) < 0.001
   % under-five mortality due to diarrheaa OR: 0.20 (0.14, 0.28) < 0.001
   IMR (per 1 000 live births) -2.29 (-2.48,-2.12) < 0.001

  1. avariable divided into quartiles
  2. bSample interpretation: under-five mortality rate is seen to decrease by 2.25 (95%CI 2.05, 2.50) with increasing quartile of proportion of population with improved water access
  3. cSample interpretation: the estimated odds ratio that increased population quartile access to water is significantly associated with increased odds of under-five child mortality due to diarrhea is 0.20 (95%CI 0.14, 0.28)
