Figure 1. Analytical flow chart for the estimation of maternal mortality for GBD 2015.

Figure 1

Ovals represent data inputs, square boxes represent analytical steps, cylinders represent databases, and parallelograms represent intermediate and final results. Numbers are steps of the prcoess. The flowchart is colour-coded by major estimation component: data preparation and overall maternal mortality in blue; cause-specific and timing-specific estimation in green; analysis and data specific to the role of HIV/AIDS in maternal mortality in pink; steps related to demographic and computational processes that ensure internal consistency in orange, and final estimates in dark blue. GBD=Global Burden of Disease. ICD=Internatinal Classification of Diseases. COD=causes of death. Epi=epidemiology. DHS=Demographic and Health Survey. CODEm=causes-of-death ensemble modelling. RR=relative risk. MMR=maternal mortality ratio. WPP=World Population Prospects. EPP=Estimation and Projection Package. RR=relative risk. Preg+=pregnant. Preg–=non-pregnant.
