H19 and coronary artery disorder: As shown in Table 4, we found that the predictive effect of plasma H19 on the risk of CAD was more prominent in females (Adjusted OR = 1.126, 95% CI = 1.021–1.241, P = 0.017), elderly (Adjusted OR = 1.115, 95% CI = 1.006–1.236, P = 0.039) and non-diabetic subjects (Adjusted OR = 1.092, 95%CI = 1.013–1.177, P = 0.021).
