  2. Diabetes prevalence data is sourced from the World Health Organisation and is compiled using local epidemiological studies and surveys. Amputation is not included here as most international studies report findings as per capita or incidence rates not as prevalence rates. Deformity is not included here as no local or international deformity data could be identified for use as a comparison. ** Prevalence data for Asia is reported as a mean value given that this study was conducted across 7 Asian countries.
