Values are n (%).
Self-C: self-reported constipation (positive answer at the direct question: ‘Do you consider yourself suffering of constipation?’); Self-C + Bristol: Self-C with Bristol score 1–2; Self-C – Bristol: Self-C with Bristol score 3–6; Rome-C: constipation defined according to the Rome III Criteria; NR: missing data.
p = 0.01 vs. Self-C+Bristol and Rome-C by multivariate analysis.
p = 0.01 vs. Rome-C by multivariate analysis.
p = 0.01 vs. Self-C and Self-C +Bristol and Rome-C by multivariate analysis.
Symptoms of outlet disorders: presence of at least one of straining at evacuation, manual manoeuvers, and incomplete defecation.
