  • Numbers express medians and 95% credible intervals in parenthesis.

  • Estimates correspond to urban populations standardised where possible to 2005. For Japan and Malaysia, estimates are indicative of 1990 and for Mongolia estimates are for a rural population in 2003.

  • Cells without estimates of prevalence indicate insufficient data to obtain estimates.

  • *Estimate obtained by extrapolation.

  • †Survey year as fitted in the model.

  • ‡Mean survey year weighted by study population size.

  • §Estimates correspond to rural populations.

  • ¶Estimates correspond to mixed populations in terms of urban/rural environmental setting.
