A cross-sectional study of pain sensitivity, disease-activity assessment, mental health, and fibromyalgia status in rheumatoid arthritis

Table 3 Multivariable associations of pressure-pain detection thresholds (PPTs) with DAS28 components

DAS28 component		Medial knee		Tibia		Sternum
DAS28 component		β	P	β	P	β	P
Patient-reported	TJC	−0.37	0.030	−0.42	0.017	−0.29	0.092
Patient-reported	VAS-GH	−0.33	0.047	−0.22	0.195	−0.38	0.029
Observed	SJC	−0.08	0.539	−0.03	0.842	−0.05	0.719
Observed	ESR	−0.07	0.614	−0.22	0.134	−0.10	0.950

Standardized β values and P values (not corrected for multiple comparisons) are shown for three regression models comparing the influence of DAS28 components on PPT. Multiple linear regression models with log-transformed PPT at each testing site as dependent variable, and TJC, VAS-GH, SJC, ESR, age, and gender as predictor variables.
