  • Continuous variables are presented as the mean ± SD; categorical variables are presented as frequencies (%); incident events were presented as the number of events (event rates). The JHS (n = 3,675) excludes those counted in the ARIC study cohort. Asian/Pacific Islanders are all Chinese American in the MESA and except for two unspecified Asian/Pacific Islanders from the ARIC study. DM duration data were available in 602 ARIC study participants, 457 MESA participants, and 348 JHS participants.
