From: Distinguishing fibromyalgia from rheumatoid arthritis and systemic lupus in clinical questionnaires: an analysis of the revised Fibromyalgia Impact Questionnaire (FIQR) and its variant, the Symptom Impact Questionnaire (SIQR), along with pain locations

Figure 1

The main effect shows that both tenderness and pain are significantly greater in fibromyalgia than in rheumatoid arthritis/systemic lupus erythematosus. However, the interaction shows that (a) this difference is greater in fibromyalgia (FM) than in rheumatoid arthritis/systemic lupus erythematosus (RA/SLE) and (b) tenderness is more severe than pain in FM, whereas pain predominates over tenderness in RA/SLE. The healthy control values are provided for background comparison. HLTH, healthy controls.
