Clinical Study

The Relationship between Mechanical Hyperalgesia Assessed by Manual Tender Point Examination and Disease Severity in Patients with Chronic Widespread Pain: A Cross-Sectional Study

Table 4

Univariate/marginal model: significance of variables at a given tender point threshold with the pain response cutoff set at 2 at the tender point examination.

Outcome variable TP > 1TP > 2TP > 3TP > 4TP > 5TP > 6TP > 7TP > 8TP > 9TP > 10TP > 11TP > 12TP > 13TP > 14TP > 15TP > 16TP > 17
