Figure 4
Box plots of the random urine Klotho/Cr by CKD stages and the relationship between the log-transformed random urine Klotho/Cr and eGFR. (a) No trend towards the lower values of the random urine Klotho/Cr with advancing stages of CKD was statistically confirmed. The lower border of the box and the upper border of the box represent the first quartile and third quartile, respectively. The whiskers indicate 1.5 times the IR above and below the 25th and 75th percentiles. Outliers (values >1.5 times the IR) are represented by closed circles. (b) A significant association between the log-transformed random urine Klotho/Cr and the eGFR was observed.
