Systemic symptoms questionnaire results. FM (white bars), LBP (grey bars) and Normal (black bars) results are shown for each domain. The x-axis shows the systems domains with the total number of questions in parentheses. The y-axis shows the number of positive responses within each domain. The error bars are the 95% confidence intervals. FM scores were higher than Normal for ENT and IBS (p ≤ 0.05), Chest, Headache, Neurological and Bladder (p ≤ 0.01), Fatigue and Musculoskeletal (p ≤ 0.001). FM scores were higher than LBP for Neurological (p ≤ 0.05), Chest (p ≤ 0.01) and Fatigue (p ≤ 0.001). Normal and LBP scores were not different.
