N = number within group; % = adjusted percent-probability weighted for the registered 2014 Thai population stratified by age, sex, area of residence (urban/rural), geographic region; eGFR < 60, decreased GFR-all causes; eGFR < 60 (DM-HT-), decreased GFR without diabetes or hypertension; eGFR < 60(DM-HT-Prot ≤ 1 +), decreased GFR without diabetes, hypertension or heavy proteinuria.
