The comparative analysis of AUC of RC and other non‐conventional lipid parameters for predicting AS showed that the discriminant ability of RC was significantly higher than that of other predictive models, including non‐HDL‐C, AIP, AI, TG/HDL‐C, CRI‐I and CRI‐II (all P for comparison < .05). Here, AIP is linked to aortic valve stenosis.
