Do infections play a role in the development of chronic inflammatory arthritis? A 14-year follow-up study of patients with early arthritis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe role of preceding infections in the development of reactive arthritis (ReA) is well known but is less studied in association with other inflammatory arthritides. Therefore, in 1979-80 we screened for infections in patients with early musculoskeletal symptoms who were referred for rheumatological consultation and assessed the role of infections and other clinical factors in the development of chronic disease in following 14 years.
methodsA total of 104 consecutive patients with suspected inflammatory musculoskeletal symptoms with a duration < 6 months were examined and screened for preceding infections in an outpatient rheumatology clinic. Follow-up evaluation was conducted after 14 years.
resultsReA, undifferentiated arthritis, and rheumatoid arthritis were the most common diagnoses at baseline and at the 14-year follow-up. Of the 80 patients participating in the 14-year follow-up evaluation, 34 (42.5%) had had evidence of infection at baseline. Twenty-four patients (30%) had developed chronic rheumatic disease. Polyarticular disease at baseline and positive rheumatoid factors predicted the development of chronic diseases. Of the patients originally diagnosed with ReA, 7.3% proceeded to ankylosing spondylitis.
conclusionAt baseline, signs of preceding infections were detected in 41% of the patients with early musculoskeletal symptoms. Preceding infections showed no association with either specific diagnosis of arthritis, except for ReA. CLINICAL TRIAL NUMBER: Not applicable.
