The Rate of Helicobacter pylori Seropositivity in a Group of Korean Patients with HLA-B27-Associated Acute Anterior Uveitis.
Article in PloS one, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeTo investigate an association between Helicobacter pylori seropositivity and HLA-B27-positive acute anterior uveitis (AAU) in Korean patients.
methodsRetrospective analysis was performed with data from 106 patients previously diagnosed with AAU without clinical evidence of spondyloarthropathy. Serum immunoglobulin G antibodies to H. pylori were measured by enzyme-linked immunosorbent assay, and HLA typing was performed using polymerase chain reaction of DNA amplification. We included 72 non-uveitis patients and 35 age- and sex-matched healthy controls in the study.
resultsOf the 106 patients with AAU, 41 (38.7%) were HLA-B27-positive, and 45 (42.5%) were seropositive for H. pylori. Patients with HLA-B27-positive AAU had a significantly lower prevalence of H. pylori seropositivity compared to those with HLA-B27-negative AAU and healthy controls (24.4% vs. 53.8%, p = 0.003; 24.4% vs. 57.1%, p = 0.004, respectively). In the non-uveitis group, however, HLA-B27-positive patients exhibited similar H. pylori seropositivity prevalence to HLA-B27-negative patients and healthy controls (45.5% vs. 55.7%, p = 0.529; 45.5% vs. 57.1%, p = 0.497, respectively). In multivariate analysis, a low prevalence of H. pylori seropositivity was significantly associated with HLA-B27-positive AAU (odds ratio = 0.340, 95% confidence interval 0.135-0.855, p = 0.022).
conclusionsOur results suggest an inverse association between H. pylori seropositivity and HLA-B27-positive AAU. Further investigation of this association is needed, given the low prevalence of H. pylori seropositivity observed in patients with HLA-B27-positive AAU.
