Under-five and neonatal mortality rates (per 1,000 live births) at the national level: actual 1980–2011; projected to 2015.

<p>National estimates by source and using the pooled data are displayed. Loess regression using a smoothing parameter of 0.5 was applied to produce the continuous series <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0103597#pone.0103597-Cleveland1" target="_blank">[51]</a>. The last set of parameter estimates for the Loess regression were utilised to project mortality rates toward 2015. The solid and semi-broken lines represent the continuous mortality estimates calculated from the two-year estimates, while the shaded area signifies the corresponding 95% confidence intervals. U5MR, under-five mortality rate; NMR, neonatal mortality rate; DHS, Demographic Health Survey; CI, confidence intervals.
