Cardiovascular risk classification according to 2019 ESC criteria in patients aged < 35 or ≥ 35 years (n = 575). Total (fatal + non fatal) CVD risk was estimated in the total population, stratified by age (< 35 or ≥ 35 years). CVD risk categories were defined according to 2019 ESC guidelines. Very high CVD risk category included T1D patients with a history of CVD, or target organ damage (proteinuria, eGFR < 30 ml/min/1.73 m2, left ventricular hypertrophy, or retinopathy), or three or more major CVD risk factors (age > 35 years, hypertension, hypercholesterolemia, smoking, obesity), or early-onset T1D of long duration (> 20 years); high risk category included all patients not included in the very high or the moderate risk category; moderate risk group included young patients (aged < 35 years) with T1D duration < 10 years without other risk factors
