Ligation of the intersphincteric fistula tract vs conventional surgery for anal fistula in Chinese patients

Figure 2 Forest plot. A: Cure rate. Forest plot depicting pooled relative risk (RR) of cure following ligation of the intersphincteric fistula tract (LIFT) vs conventional surgery, with 95% confidence intervals (CIs). Each square represents an individual study estimate, and the diamond indicates the overall pooled effect; B: Recurrence rate. Forest plot depicting the pooled RR for recurrence between LIFT and conventional surgery, with 95%CIs. A lower RR indicates reduced recurrence in the LIFT group; C: Complication rate. Forest plot comparing the complication rates between LIFT and conventional surgery. The pooled RR and 95%CIs demonstrate the safety profile of LIFT; D: Postoperative pain. Forest plot of pooled mean differences in the postoperative pain scores (Visual Analog Scale) between LIFT and conventional surgery, with 95%CIs. Negative values favor LIFT.
