National Campaign to Detect Diabetes Mellitus. Brazil, 2001. a Range corresponds to the 95% confidence interval of each estimate from the probabilistic sample. b Fasting was defined as absence of food ingestion 4 hours prior to capillary glucose test. c Range corresponds to an arbitrary estimate of the authors. d Fasting glucose ≥ 5.6 mmol/l or a casual glucose ≥ 7.8 mmol/l. e These subjects knew their previous diabetes diagnosis; however, they had not provided that information when asked about it during screening program. f Range expressed as an additional percentage of national costs. | ||
