Correlation coefficients between clinical variables at baseline and radiological scores; p<0.05, *p<0.01, †not significant. Values are given for the whole group (n=155), except wherever significant differences were found between the two treatment groups

SSZ, group with sulfasalazine treatment only; COMBI, group with combination treatment (sulfasalazine, methotrexate, prednisolone); CRP, C reactive protein; ESR, erythrocyte sedimentation rate; IgM RF and IgA RF, IgM and IgA rheumatoid factor; SHS, Sharp score (van der Heijde modification).
