Table 3 Multiple logistic regression analyses of potential predictors of anal fistula plug success.

Variable	OR (95% CI)	P
Hemoglobin (each 1 g/L increase)	0.978 (0.949–1.007)	0.138
Duration of fistula (mo, ≥6/	3.187 (1.361–7.466)	0.008
Distance between external Opening and anal verge (each 1 cm increase)	0.939 (0.675–1.305)	0.707
OR – odds ratio; CI – confidence interval. Multiple logistic regression analysis showed that the duration of anal fistula ≥6 months was an independent risk factor for treatment failure using the anal fistula plug (OR=3.187, 95% CI: 1.361–7.466, =0.008).
