Fig. E-1
Risk of revision surgical procedure, reoperation, and revision for mechanical failure and aseptic
loosening according to BMI, including all shoulder arthroplasties not performed for rotator cuff
(RC) arthropathy. The dotted lines indicate 95% CIs. Analysis was performed using smoothing
spline parameterization.

Fig. E-2
Risk of infection (overall and superficial), periprosthetic fracture, and shoulder dislocation
according to BMI, including all shoulder arthroplasties not performed for rotator cuff (RC)
arthropathy. The dotted lines indicate 95% CIs. Analysis was performed using smoothing spline
parameterization.
