  1. n number of patients, SD Standard Deviation, RF Rheumatoid Factor, NA Not applicable. P values for difference between means were compared using Mann Whitney U test aFor comparison of gender, Chi-square test was used for categorical variable. *ESR was measured in mm/h. **Assay cut off for CRP = 6 mg/L and tested using particle agglutination test, ***Assay cut off for RF = 20 IU/ml and tested using particle agglutination test.
