HLA class II is associated with distal interphalangeal osteoarthritis.

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
objectiveTo investigate whether there is an association between HLA class II and distal interphalangeal osteoarthritis (DIP OA).
methodsThe study group consisted of consecutive patients with and without DIP OA aged between 40 and 70 years. DIP OA was diagnosed by radiology. These patients were referred to an "Early Arthritis Clinic" (EAC) with different types of arthritis at an early stage. Patients with rheumatoid arthritis, systemic lupus erythematosus, spondyloarthropathies, and psoriatic arthritis were excluded for the purpose of this study. DNA typing for HLA-DR and x ray examination of the hands were performed at enrollment in the EAC. To establish whether the study group was representative of the Dutch population, a population based study in Zoetermeer (n=3243) for the prevalence of DIP OA and blood donors in the Leiden area (n=2400) for the HLA-DR antigen frequencies were used as references.
resultsFifty five patients (33%) of the total study group (n=166) had DIP OA. The prevalence of DIP OA and frequency of the HLA-DR alleles were similar to those of the two reference groups. Within the study group an association between DIP OA and HLA-DR2 and DR4 with respectively odds ratios of 2.4 (95% confidence interval (CI) 1.1 to 5.0) and 0.3 (95% CI 0.1 to 0.7) was found. No association was found between other HLA-DR alleles and DIP OA.
conclusionThe study group is a representative sample of the Dutch population. The HLA-DR2 allele was more common in patients with DIP OA. Furthermore, an inverse relation was observed between DIP OA and HLA-DR4. The results confirm findings from other investigations implicating HLA-DR2 as a risk factor in the development of DIP OA.
