RCAN1 and coronary artery disorder: The associations of the six hub RNAs (lnc‐ILK‐8:1, lnc‐OTX1‐7:1, lnc‐RCAN1‐6:1, GIMAP8, SUV420H1 and PIGV) with SSH were analysed using a logistic regression model adjusting for dietary factors and history of coronary heart disease, which were found to be associated with SSH, although the differences of these two variables did not reach the statistically significant level in our study.
