Data are presented as n (%) for categorical variables and mean ± SD (range) or median (25 percentile, 75 percentile) for continuous variables, depending on the skewedness of the distributions
aFor patients> 18, the CKD-EPI equation was used to estimate GFR. For patients< 18, the Schwartz 2009 equation was used to estimate GFR
