 note = {We can use the 1987 traditional (4 of 7) format, the 1987 classification tree or the old ARA criteria for rheumatoid arthritis (RA). The performances of each of the classification methods were treated in the 112 RA and 98 non-RA patients whose disease duration was less than 1 year. It was the classification tree that number of patients misclassified were most less. It was 85.7% sensitivity and 88.8% specificity for RA when compared with non-RA. However, in the RA patient whose disease duration was less than 3 months, the sensitivity was 75%. In addition, we presented a revised classification tree that added radiographic changes in feet and swelling of the metatarsophalangeal joints. These cases were treated with Gold as a first choice generally. The radiographic change of bilateral wrist was evaluated with Larsen's standard films. The proportion of grade II or more had been 24% in less than 1 year pretreatedly, but its proportion increased 60% after 2 years and 74% after 4 years posttreatedly. We compared the patients that treated with disease modified antirheumatic drugs (DMARDs) in disease duration less than 6 months with the patients in its more than 6 months. As a results, the former was more late the radiographic changes than the latter.},
