Comparison 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)
