Changes in CDAI in adjusted data using inverse probability of treatment weighting. Changes in CDAI in all patients (a), patients aged < 65 years (b), patients aged 65–74 years (c), and patients aged ≥ 75 years (d). Data are presented as mean ± 95% confidence interval (error bars). CDAI = clinical disease activity index; yr = years; TNFi = tumor necrosis factor inhibitors; ABA = abatacept; TCZ = tocilizumab
