Increasing and decreasing global DALYs for causes from 1990 to 2005 (A) and 2005 to 2013 (B). Within each tree map, the size of the rectangle for each cause is proportional to the magnitude of the decrease or increase in DALYs for each cause. Dark shading show statistically significant changes and light shading shows changes that are not significant.

Total DALYs, crude DALY rates, and age-standardised DALY rates from 1990 to 2013 Changes in global DALYs caused by communicable, maternal, neonatal, and nutritional disorders, non- communicable diseases, and injuries shown in terms of numbers of DALYs (A), DALY rates per 100 000 people (B), and age-standardised DALY rates per 100 000
people (C). The difference in trends between A and B is caused by population growth and the difference between B and C becaus e of changes in the percentage distribution of the population by age. Shaded areas show 95% uncertainty intervals. DALY=disability-adjusted life-years.

YLL and YLD cause composition of DALY rates by sociodemographic status vigintile. The epidemiological transition based on predicted YLL and YLD rates per 100 000 people as a function of the level of sociodemographic status by vigintile and broken down into GBD level 2 causes. These predicted levels control for variation explained by year and country. YLL= years of life lost. YLD=years lived with disability. GBD=Global Burden of Disease.
