Median and interquartile range were used for continuous variables and count and proportion were used for categorical variables. P-values were reported from the Mood’s median test for continuous variables and chi-sqaured test for categorical variables. FRS Framingham risk score; DXA dual-energy X-ray absorptiometry.
