5. Figure 4
The proportion having at least moderate symptom severity (mean scores on GSRS-IBS domains ≥4) in the groups with altered vs normal rectal perception, as well as the proportion of patients having clinically significant anxiety and depression according to HAD (score on HAD anxiety or HAD depression ≥11). Shown also is the proportion of patients in the respective groups having a GSRS mean total score ≥4, meaning at least moderate GI symptom severity overall (total GI symptoms [sx]). *P < .05; **P < .01; ****P <
