This index is defined as the lowest of either: a) percent change in TJC, b) percent change in SJC, or c) median percent change of the remaining 5 ACR core criteria (HAQ-DI, CRP, PAAP-VAS, PtGADA-VAS, or PhGA-VAS). A participant with an ACR-N of \"X\" has improvement of at least \"X%\" in tender and swollen joints and a median improvement of at least \"X%\" in the 5 remaining ACR core criteria. Since ACR-N is a continuous measure, the mean values are reported instead of the originally registered percentage of participants.","dispersionType":"Standard Deviation","groups":[{"description":"Participants on background methotrexate therapy who were administered 1 mg, 2 mg, 4 mg baricitinib (LY3009104) capsule or identical placebo capsule, orally once daily for 12 weeks in Part A received 4 mg baricitinib (LY3009104) and 1 placebo tablet orally once daily for 52 weeks in Part B.","id":"OG000","title":"Combined 4 mg Baricitinib (LY3009104)"},{"description":"Participants on background methotrexate therapy who were administered 1 mg, 2 mg, 8 mg baricitinib (LY3009104) capsules orally once daily for 12 weeks in Part A received 2 x 4 mg baricitinib (LY3009104) tablets orally once daily for 52 weeks in Part B.","id":"OG001","title":"Combined 8 mg Baricitinib (LY3009104)"}],"paramType":"MEAN","populationDescription":"All participants who received any study drug in Part B and had baseline and at least one post baseline ACR-N response measure.
