Fig. 5: Change in total bilirubin level (mg/dl) over time by UGT1A1 (rs4148325) genotype in A Sarilumab + DMARD-treated patients and B Placebo + DMARD-treated patients.

Functional canonical correlation analysis (FCCA) was applied to test the association between the change in total bilirubin level over time and rs4148325 genotype (Interaction: rs4148325 genotype × treatment, p = 0.03).
