Fig. 2From: Clinical outcomes and effect on intraoperative blood loss and postoperative pain of patients undergoing retroperitoneal laparoscopic partial nephrectomy for complex renal tumorsComparison of quality of life scores 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 quality of life scores (points); before and after treatment, the patients’ quality of life scores of the RLPN group were 56.81 ± 6.54 and 72.31 ± 6.52, respectively, and those of the OPN group were 56.87 ± 6.48 and 65.61 ± 6.27, respectively; the single asterisk (*) indicated that before and after treatment, the patients’ quality of life scores of the RLPN group were clearly different (t = 8.223, P < 0.001); double asterisk (**) symbol indicated that before and after treatment, the patients’ quality of life scores of the OPN group were clearly different (t = 4.942, P < 0.001); and triple asterisk (***) symbol indicated that after treatment, the patients’ quality of life scores of both groups were clearly different (t = 3.704, P < 0.05)Back to article page
