Human papillomavirus infection and the risk of uveitis: a propensity-score-matched electronic health record study.
Observational study in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Uveitis is a leading cause of preventable blindness in working-age adults. While herpesviruses are established causes, the potential contribution of human papillomavirus (HPV), a prevalent infection with immunomodulatory properties, remains unexplored. This study aims to investigate whether prior HPV infection is associated with an increased risk of developing uveitis using a large-scale, real-world dataset. In this multicenter, retrospective cohort study, adults aged ≥ 18 years from the TriNetX US Collaborative Network. A total of 460,932 HPV patients and 460,932 propensity score-matched controls without HPV were included after exclusions for malignancy, prior uveitis, or insufficient follow-up. HPV infection was identified by ICD-10-CM codes. Propensity score matching balanced demographics, comorbidities, socioeconomic and behavioral risk factors, and healthcare utilization. Patients were followed for up to 15 years for incident uveitis. Stratified analyses were conducted by age, sex, race, and comorbidities. Sensitivity analyses tested alternative HPV definitions, different washout periods, follow-up horizons, and matching approaches. Incident uveitis defined by ICD-10-CM codes, with hazard ratios (HRs) and 95% confidence intervals (CIs) estimated. HPV infection was associated with an elevated risk of uveitis (HR = 1.30; 95% CI: 1.19-1.42, p < 0.05). Risks persisted across sensitivity analyses, with HRs ranging from 1.23 (95% CI: 1.04-1.47) to 1.46 (95% CI: 1.34-1.59). Subtype analyses showed significant associations with iridocyclitis (HR = 1.27; 95% CI: 1.16-1.39) and unspecified chorioretinal inflammation (HR = 1.49; 95% CI: 1.06-2.09). Stratified analyses demonstrated higher risks among patients aged ≥ 65 years (HR = 1.44; 95% CI: 1.13-1.83), males (HR = 1.63; 95% CI: 1.40-1.89). In patients having both HPV and herpes zoster infection, risk of uveitis was 2.98-fold higher than controls (95% CI, 1.66-5.35). Prior HPV infection was associated with subsequent uveitis-related diagnoses in this large observational study. However, given the reliance on administrative coding, potential diagnostic heterogeneity, and residual confounding, these findings should be interpreted cautiously. Further prospective studies with clinically validated uveitis phenotypes are needed to clarify the nature and clinical relevance of this association.
