Fig. 2From: Circulating cell-free nucleosomes as biomarker for kidney transplant rejection: a pilot studyCourse of CCFN values in 40 kidney transplant recipients (a). Depicted are the concentrations of total CCFN (H3) and ODs of b CCFN with H3K36me3 and c CCFN with H3 citrulline over time. OD, optical density. N.B.: CCFN box whiskers represent minimal and maximal values. The middle line of the box represents the median and the upper and lower borders represent the 25 and 75% percentile, respectively (*p < 0.05, **p < 0.01, ***p < 0.001)Back to article page
