“…Duration of morning stiffness does not correlate with PtGA (21) and when compared to the DAS28, the PtGA was 41% more likely to be concordant than discordant (15). Education may affect patient ratings of disease activity (14), comorbid disease increases the PtGA (14), and support groups may decrease PtGA (22). In a study of 24 patients, the PrGA correlated with the PtGA and pain scores (R = 0.2–0.7), with the Health Assessment Questionnaire (HAQ; R = 0.3–0.7), and with ESR (R = 0.2–0.4) (23).…”
