DMARD indicates disease-modifying anti-rheumatic drug; PY, patient-year.
a Events were calculated for all patients exposed to etanercept from the start of the randomized phase in the etanercept-plus-methotrexate group and from the start of the extension in the DMARD-plus-methotrexate group.
b Benign, malignant, and unspecified.
c Excluding injection site reactions.
