Box plots showing the median (line), the interquartile range (box) and 10th–90th percentiles (whiskers) of preoperative and postoperative (1–3 months after surgery) growth hormone levels, insulin-like growth factor 1 (IGF-1) levels, soluble α-Klotho protein (sKl) levels of all patients (n = 55), for Group A (n = 39), Group B (n = 7), and Group C (n = 9), respectively. Pre- and postoperative GH levels were compared using the Wilcoxon signed rank test. *p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001.
