Irritable bowel syndrome (IBS) symptom scores (mean, SEM) shown for responders (R) and non-responders (NR), as measured in IBS questionnaire (VAS 0–100 mm), completed at the time points shown. For data in this table (and similarly in all tables), overall score is treated as the primary outcome and therefore no adjustments are made for multiple comparisons. “Unadjusted” comparisons for individual symptoms significant at the 0.1% level (p<0.001) assumed significant at the 5% level if multiple comparison adjustments were made.
*p<0.05; **p<0.01; ***p<0.001; †p>0.05 (R v NR).
BH, bowel habit; HT, hypnotherapy.
