Finally, there were significantly more individuals being given insulin (P<0.001), with a history of revascularization, with a Canadian Cardiovascular Society (CCS) grading of angina pectoris ≥2, with T‐wave inversions (P<0.01 for all), or with type 2 diabetes in the SCD group compared with the SCD‐free group (P<0.05; Table S8). Here, INS is linked to Schnyder corneal dystrophy.
