Multivariate linear regression analysis: correlation between clinical variables and rheumatoid factor (RF)/anticyclic citrullinated peptide (anti-CCP) antibody titers, adjusted for sex.
| RF Titer | Anti-CCP Antibody Titer | ||||||
|---|---|---|---|---|---|---|---|
| b (SE) | ß | p | b (SE) | ß | p | ||
| Age | 8.48 (3.49) | 0.241 | 0.017 | Age | 10.20 (5.44) | 0.218 | 0.066 |
| RF | 0.68 (0.29) | 0.235 | 0.020 | Anti-CCP antibody | 1.46 (0.40) | 0.435 | 0.001 |
Mean prednisolone dose for previous 1 month, DAS28, disease duration, and the use of anti-TNF agents were tested and found to be not significant (p > 0.05). DAS28: Disease Activity Score 28; anti-TNF agents: anti-tumor necrosis factor agents.
