{"doi":"10.1002/art.1780310302","title":"The american rheumatism association 1987 revised criteria for the classification of rheumatoid arthritis","abstract":"The revised criteria for the classification of rheumatoid arthritis (RA) were formulated from a computerized analysis of 262 contemporary, consecutively studied patients with RA and 262 control subjects with rheumatic diseases other than RA (non-RA). The new criteria are as follows: 1) morning stiffness in and around joints lasting at least 1 hour before maximal improvement; 2) soft tissue swelling (arthritis) of 3 or more joint areas observed by a physician; 3) swelling (arthritis) of the proximal interphalangeal, metacarpophalangeal, or wrist joints; 4) symmetric swelling (arthritis); 5) rheumatoid nodules; 6) the presence of rheumatoid factor; and 7) radiographic erosions and/or periarticular osteopenia in hand and/or wrist joints. Criteria 1 through 4 must have been present for at least 6 weeks. Rheumatoid arthritis is defined by the presence of 4 or more criteria, and no further qualifications (classic, definite, or probable) or list of exclusions are required. In addition, a \"classification tree\" schema is presented which performs equally as well as the traditional (4 of 7) format. The new criteria demonstrated 91-94% sensitivity and 89% specificity for RA when compared with non-RA rheumatic disease control subjects.","journal":"Arthritis & Rheumatism","year":1988,"id":6790,"datarank":1.4846506000821846,"base_score":9.897670667214562,"endowment":9.897670667214562,"self_citation_contribution":1.4846506000821846,"citation_network_contribution":0.0,"self_endowment_contribution":1.4846506000821846,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":19883,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.1131,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"1988-03-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":62637,"name":"Steven M.
