Global prevalence estimates of IGT by IDF region [9]. Data source: IDF Diabetes Atlas – 8th Edition. Percentages represent unadjusted regional prevalence estimates. Numbers in parentheses represent the estimated number of individuals affected by IGT in each region. Prevalence estimates calculated by the IDF using a generalised linear regression model. A variety of country-level data sources were included, mostly from peer-reviewed journals and national health surveys.
