Fig. 2. Heat map of the Spearman rank correlations of Hamilton Depression Rating Scale (HAMD) and structural factor scores with the main bowel symptoms of irritable bowel syndrome with diarrhea. Score of HAMD positively correlated with the scores of main bowel symptom score (r = 0.127, P = 0.010), degree of pre-defecation abdominal pain/discomfort (r = 0.101, P = 0.040) and improvement of abdominal pain/discomfort after defecation (r = 0.183, P < 0.001). Score of mental disorders positively correlated with the scores of main bowel symptom (r = 0.154, P = 0.002), degree of pre-defecation abdominal pain/discomfort (r = 0.172, P < 0.001) and degree of improvement of abdominal pain/discomfort after defecation (r = 0.135, P = 0.006). Scores of anxiety/somatization and sleep disturbances also positively correlated with the score of degree of improvement of abdominal pain/discomfort after defecation (r = 0.144, P = 0.004; r = 0.150, P = 0.002). *P < 0.05, **P < 0.01. abd., abdominal.
