  1. Data are presented as β (95%CI) P-value. Model I, linear analysis; Model II, non-linear analysis. LRT test, logarithmic likelihood ratio test. (p value < 0.05 means Model II is significantly different from Model I, which indicates a non-linear relationship). Adjusted for: age; duration; etiology; scar location; scar length; scar width; echogenicity; subclinical fistulous tracts; supracutaneous height; blood flow type.
