HSCL-10: Hopkins Symptom Checklist 10; WHO-5: World Health Organization 5 Well-Being Index; FSS: Fatigue Severity Scale; LDL: low-density lipoprotein; HDL: high-density lipoprotein; CRP: C-reactive protein; TSH: thyroid-stimulating hormone; T4: thyroxin. Linear regression with IBS-SSS and GSRS-IBS as the independent variables, and the other variables one by one as covariates, adjusted for gender and age (gender and age presented unadjusted in the first two rows). q values are Benjamini-Hochberg adjusted to preserve false discovery rate for twenty-two hypotheses.
