  1. *Log-transformed CRP results were back transformed; p-value <0.05 was taken to indicate statistically significant differences between two groups; adjusted mean changes from baseline under treatment with etanercept or adalimumab (95% CI). Outcome differences were adjusted for baseline status (see Methods).
