It is known from the COMET-trial that patients who start Enbrel treatment early have a great chance of reaching clinical remission and radiographic nonprogression. It is still unclear, however, how many patients with early arthritis achieve remission and radiographic nonprogression under the conditions of routine rheumatologic care and the local recommendations of Enbrel treatment (pre-treatment of at least 2 DMARDs, one of them MTX). Therefore, no robust x-ray data are available to show/demonstrate * the average extent of x-ray damage in routine patients on Enbrel outside clinical studies. * if the outstanding effect on structural damage of Enbrel can be reproduced in routine practice. * that the 'Silent Progressor' is an issue relevant not only in clinical trials, but also for day-to-day decision making. * the optimal onset of Enbrel treatment in the course of the disease to prevent radiographic damage

Change From Baseline in Van Der Heijde Total Modified Total Sharp Score (mTSS) or Adapted mTSS at End of Phase 1 (Week 78): Efficacy Analysis Set (EAS)
To assess radiological damage mTSS score was used in participants with rheumatoid arthritis and mTSS adapted score was used in participants with psoriatic arthritis. Radiographs of the hands and feet were assessed by central raters. Total mTSS score range was 0 (no radiological damage) to 448 (extreme radiological damage); and total mTSS adapted score range was 0 (no radiological damage) to 528 (extreme radiological damage), where higher mTSS and mTSS adapted scores indicate a worse health status in participants with rheumatoid arthritis and participants with psoriatic arthritis, respectively.

FFbH is a self-administered patient questionnaire composed by 18 questions on functional ability in activities of daily living. Each question was answered by the participant as "Yes, I can perform the activity without difficulty" (score assigned =2), "Yes, but with difficulties" (score assigned =1) and "No or only with external help" (score assigned =0). Final FFbH score (%) was then computed according to formula: (Sum of scores\*100) divided by (2\*number of valid answers), ranging between 0 (no functional capacity) to 100 (full functional capacity); higher scores indicate better daily activities. FFbH functional remission was defined as FFbH functional capacity of \>= 83%.
