"Note: The data sources include population-based epidemiological studies, disease registers, and surveillance and notification systems, but exclude death registration data (see tables 3.1 and 3.2). Where possible, regional and global totals refer to numbers of separate studies, or country-years of reported data from surveillance or notification systems. For some causes, regional subtotals for the Disease Control Priorities Project regions were estimated from subtotals for WHO regions and subregions. See text for more information on data sources for specific causes.",,,,,,,,
a. Global totals may include global review studies not counted in regional subtotals.,,,,,,,,
"b. Totals refer to numbers of countries for which data were available, not to total data sets or country-years.",,,,,,,,
c. Regional subtotals were estimated from the current distribution of studies in the WHO sexually transmitted infection (STI) surveillance database.,,,,,,,,
"d. Regional subtotals were estimated from numbers of studies by WHO region, rather than by re-accessing original databases.",,,,,,,,
e. Country-years of data available for 133 countries.,,,,,,,,
f. Approximate estimate from current WHO database; original extraction from surveillance data sources is not available.,,,,,,,,
"g. Country-years of surveillance reports (approximate, minimum estimate for Latin America and the Caribbean).",,,,,,,,
h. Estimate based on final published literature review.,,,,,,,,
i. Regional distribution of the 419 national studies used is assumed to be similar to that of the current 442 national studies in the WHO malnutrition database.,,,,,,,,
j. Total of 100 population-based registries in 50 countries.,,,,,,,,
k. Approximate minimum estimate. Several global reviews were used; studies were not separately counted.,,,,,,,,
"l. Actual numbers of studies used exceed the minimums shown here, based on summed table entries for specific causes regardless of whether counts were of data sets or of countries.",,,,,,,,
