n denotes number of patients fulfilling criteria for analysis.

Values in bold demonstrate statistical significance with p value <0.05.

*Defined as self-reported global fistula rating test/retest scores differing by no more than 1 point, no fistula flare-up and same test/retest Harvey-Bradshaw criteria.

†Defined as self-reported global fistula rating retest score ≥3 units lower than the test score.

‡Defined as self-reported global fistula rating retest score ≥3 units higher than the test score.
