Contribution of changes in the levels of determinates of health (health interventions, social and environmental determinants) to reductions in U5MR, 1990–2010 (A).

<p>Out of 768 models run, the contribution of factor level changes averaged 89%. Of these, half included a variable for fertility (Log of TFR lagged 5 years), and half did not out of concern for endogeneity. The decomposition to the right shows how these improvements averaged a breakdown by indicator. Details of this latter composition are shown in Table A in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0144908#pone.0144908.s001" target="_blank">S1 Appendix</a>. For uncertainty ranges around each estimate see Figure B in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0144908#pone.0144908.s001" target="_blank">S1 Appendix</a>.</p

Relationship between both Log (U5MR) and Log (MMR) and Log (GDP per capita).

<p>The well-known Preston relationship is clearly visible, with correlation coefficients of between -.8 and -.9. A line of best fit curve is added showing a similar slope for both years, as well as a shift rightward and downward in 2010 compared to 1990. There are 170, 179, 162, 173 countries shown respectively (A-D).</p

Defining research to improve health systems.

<p>*How amenable the research outputs are to adaptation, scaling up or use or in other contexts or locations.</p

Examples of research questions for the three research domains.

<p>*As noted above, depending on how the question is phrased and the research is designed; some of these questions can be addressed in several research domains.</p
