Distribution of Larsen scores at 5 years in all subjects (A) and in subjects with erosions (B), according to baseline antibody status in the prospective cohort. Values are presented as box and whisker plots, where the boxes represent the interquartile range, the lines within the boxes represent the median Larsen score, the whiskers represent the range from the smallest to the largest score, and the circles represent outliers. 1 represents subjects who were RF+ and anti-CCP+ (P < 0.0001 versus subjects who were RF− and anti-CCP−, both in the total group and in the group with erosions). 2 represents subjects who were RF− and anti-CCP+ (P < versus subjects who were RF− and anti-CCP− in the total group and P = 0.0001 versus subjects who were RF− and anti-CCP− in the group with erosions). 3 represents subjects who were RF+ and anti-CCP− (P = 0.90 versus subjects who were RF− and anti-CCP− in the total group and P = 0.85 versus subjects who were RF− and anti-CCP− in the group with erosions). 4 represents subjects who were RF− and anti-CCP− (referent).
