Fig. 4

Proportion 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 averages
