Apart from the early phase of treatment scale up, when the mortality of PLHIV on ART was often very high, mortality declines have been observed in PLHIV both on and off ART.
The MI ratio can be interpreted as a marker of the intensity of early diagnosis in different countries, as in the period under analysis its variation depended mostly on sharp increases in incidence, especially before mortality declines could be observed.
Our data suggests that there was no significant decline observed in neonatal mortality trends in the study period.
As compared to the period before 2002, an acceleration of mortality decline can be observed in nearly all age-groups, but was particularly noteworthy among the elderly.
Annual percent changes for overall testicular cancer mortality rates were decreasing in all study populations, with the greatest decline observed in Sweden −4.2%, (−4.8; −3.6) and China −4.9%, (−6.5; −6.5).
The sustained decline observed in many countries after 1999 seems to indicate that breast cancer mortality will continue to decrease beyond 2006.
However, in some regions, mild, subclinical, vitamin A deficiency is present in an important part of the population and it is possible that its provision can have some effect on the current declining mortality observed in some areas.
Our data also show that the level of food consumption in older flies is remarkably lower in comparison to feeding levels in early-life (up to day 14), and more experiments will be required to understand how this lowered nutritional intake may contribute to declining mortality rates observed in late-life [38].
Stage 4 features low, still declining mortality, as observed in developed countries after World War II (19).
In our study a decline in mortality was observed in almost all regions; this decline was more pronounced among the European and Oceanic countries, with the greatest changes observed in Sweden −4.2%, (−4.8; −3.6) and China −4.9%, (−6.5; −6.5).
