All determinations were performed in the fasting state. CHD: coronary heart disease; HDLc: high density lipoprotein cholesterol; LDLc: low density lipoprotein cholesterol; BUN: blood urea nitrogen; Date presented as mean±SD; Spearman correlation was used to analyze the relationship between periostin level and variables.
