Participant Characteristics
Participant characteristics are shown in Table 1. Overall, there were 3297 participants (T1DX
n=1283; DPV n=2014) with an age range of 60.0-93.6 years. Participants in the two registries
were similar in gender (48% male), BMI (mean 27 kg/m2
), and prevalence of obesity (25% with
BMI >30 kg/m2
). T1DX participants were slightly younger at time of enrollment compared with
DPV (mean age 67.3 vs. 70.8 years; 99% CI of difference, 2.8 to 4.1 years); 73% (n=935) vs.
47% (n=937) were between the ages of 60 and 70 years, and 27% (n=348) vs. 53% (n=1077)

were 70 years or older. However, mean duration of diabetes at enrollment was greater for T1DX
participants (32.3 vs 28.8 years; 99% CI of difference 2.0 to 5.0 years). The use of
antihypertensive medications, including ACE-I and ARBs, and statins were more common in the
T1DX (85% vs 62% and 68% vs 40%, respectively; 99% CI of differences, 18% to 26%, 10%
to 19%, and 23% to 32%, respectively; Table 1).
