Footnotes to table:

ESR = The Westergren erythrocyte sedimentation rate

Acute-PR = The Acute-Phase Response (Orosomucoid or C-reactive protein (CRP))

Pain Score = the patient's self perceived pain severity as evaluated on a visual analogue scale

Physic. F = Physical Function assessed by self completed questionnaires on the degree of difficulty in performing specified tasks of daily living

Tender JC = Tender Joint Count = number of painful joints at rest with pressure.
