  • AE, adverse events; CZP, certolizumab pegol; ER, event rate (includes repeat occurrences of the same AE in individual patients, with the denominator being the total duration of exposure); IR, incidence rate (the number of new cases per 100 PY, with the denominator being the exposure duration up to the first occurrence of a particular AE); MACE, major adverse cardiovascular event; N/A, not available, due to number of events being greater than the number of time units; NMSC, non-melanoma skin cancer; OI, opportunistic infection; OLE, open-label extension; pts, patients; PY, patient-years; RCT, randomised controlled trial; SAE, serious adverse event; SIE; serious infectious event.
