Figure 1.
Comparison of ovarian-related indexes (∗Note: in Figure 1, the abscissa was before and after treatment from left to right, respectively. The black area indicated the experimental group, and the gray area indicated the control group. # indicated P < 0.001). (a) PI. No significant difference was found in PI between both groups before treatment (1.49 ± 0.21 vs 1.50 ± 0.23, P > 0.05). After treatment, compared with the control group, PI of the experimental group was obviously higher (2.34 ± 0.35 vs 1.87 ± 0.25, P < 0.001). (b) RI. No significant difference was found in RI between both groups before treatment (0.90 ± 0.11 vs 0.91 ± 0.12, P > 0.05). After treatment, compared with the control group, RI of the experimental group was obviously lower (0.68 ± 0.10 vs 0.78 ± 0.12, P < 0.001). (c) OAV. No significant difference was found in OAV between both groups before treatment (3.98 ± 0.35 vs 3.96 ± 0.36, P > 0.05). After treatment, compared with the control group, OAV of the experimental group was obviously higher (6.05 ± 0.45 vs 5.10 ± 0.45, P < 0.001). (d) S/D. No significant difference was found in S/D between both groups before treatment (3.00 ± 0.24 vs 3.02 ± 0.28, P > 0.05). After treatment, compared with the control group, S/D of the experimental group was obviously lower (2.10 ± 0.12 vs 2.58 ± 0.20, P < 0.001). (e) PSV. No significant difference was found in PSV between both groups before treatment (0.79 ± 0.15 vs 0.78 ± 0.14, P > 0.05). After treatment, compared with the control group, PSV of the experimental group was obviously higher (2.29 ± 0.20 vs 1.85 ± 0.23, P < 0.001). (f) Thickness of endometrium. No significant difference was found in the thickness of the endometrium between both groups before treatment (3.55 ± 0.14 vs 3.59 ± 0.15, P > 0.05). After treatment, compared with the control group, the thickness of the endometrium of the experimental group was obviously higher (5.01 ± 0.26 vs 4.66 ± 0.19, P < 0.001).
