3.8 Symptom recurrence rate
Compared to the women in the surgery group, those in the HIFU group had a lower symptom recurrence rate, but the results did not reach statistical significance, with an overall RR of 0.95 (95% CI, 0.41 to 2.23, p=0.91, I2=0%) (Fig. 5). The symptom recurrence rate ranged from 0 to 12% in the HIFU group and from 0 to 17.2% in the surgery group.
