Fig. 4From: Development and validation of algorithms to classify type 1 and 2 diabetes according to age at diagnosis using electronic health recordsProportion of all diabetes cases classified as type 1 by age at diagnosis in the validation cohort.* This proportion is calculated as the percentage of people in the cohort with diabetes classified as type 1 using the reference standard (dashed line), as well as high sensitivity for type 1, optimized, and high positive predictive value for type 1 algorithms (see Table 4 for descriptions)*smoothed using 15-year moving averagesBack to article page
