Interaction between ethnicity and age at diagnosis of diabetes (P < 0.0001 for interaction) in the risk of cardiovascular events among adults in Ontario, Canada. Hazard ratios of cardiovascular events (coronary artery disease, congestive heart failure, stroke, peripheral revascularization, and lower extremity amputation) are shown for young- and usual-onset diabetes compared to matches without diabetes, stratified by ethnicity (Chinese, South Asian, general population). See Additional file 1: Figure. S2 for secondary outcomes. *Events and event rates pertain to the cases. Event rates are per 100,000 person-years
