[Importance and value of roentgen studies as outcome criteria in rheumatoid arthritis].
In order to evaluate the objectivity and validity of radiographic parameters in rheumatoid arthritis (RA) we studied 56 patients with definite RA. Inter-observer variation was assessed comparing the scorings (Larsen classification) of two independent experienced observers. Total radiographic scores were highly significantly correlated (r = 0.89). Yet, we could not find relevant associations between radiographic findings and clinical outcome parameters (pain, morning stiffness, dexterity, grip strength, and patient's overall assessment). Thus, hand radiographs in RA provide highly reproducible results. Its validity concerning patient outcome, however, has to be interpreted very carefully.
