Fig. 1From: Clinical outcomes and effect on intraoperative blood loss and postoperative pain of patients undergoing retroperitoneal laparoscopic partial nephrectomy for complex renal tumorsComparison of renal GFR levels of the affected side before and after treatment between the two groups (\( \overline{\mathrm{x}} \) ± s). The horizontal axis indicated before and after treatment, and the vertical axis indicated the GFR level values in ml/min; before and after treatment, the patients’ renal GFR level values of the affected side of the RLPN group were 43.37 ± 6.83 and 38.26 ± 4.97, respectively, and those of the OPN group were 43.42 ± 6.91 and 33.14 ± 5.07, respectively; the single asterisk (*) symbol indicated that before and after treatment, the renal GFR level values of the affected side of the RLPN group were clearly different (t = 2.964, P < 0.05); double asterisk (**) symbol indicated that before and after treatment, the renal GFR level values of the affected side of the OPN group were clearly different (t = 6.116, P < 0.001); and triple asterisk (***) symbol indicated that after treatment, the renal GFR level values of the affected side of both groups were clearly different (t = 3.601, P < 0.05)Back to article page
