Inequalities in under-five and neonatal mortality by wealth and education markers for selected years, with 95% confidence intervals and p-values for trend.

Notes: See File S1 for full results. U5MR, under-five mortality rate; NMR, neonatal mortality rate; CI, confidence interval; RR, rate ratio; RD, rate difference; RII, relative index of inequality; SII, slope index of inequality. The small number of observations and possible non-linear relationships implies that the trend estimates should be treated with caution. Additionally, since the bounds of the CI depend on the mean of mortality, comparisons over time must be treated cautiously.1Trend regressions with all observations included.2Trend regressions with the last 2 periods (i.e. 2008–09 and 2010–11) excluded from the sample.
