Demography in Swiss paediatric uveitis: a retrospective cohort study.
Article in Journal of ophthalmic inflammation and infection, 2024. 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
introductionPaediatric uveitis is a rare disease. It can affect any segment and have various etiologies, including infectious, autoimmune, and masquerade diseases. The pupose of this study is to analyse and present the demographic data in paediatric uveitis in a Swiss cohort. Knowledge of local demography may guide targeted work up and treatment.
methodsSingle center retrospective study from January 2012 to June 2022. Patients under 18 years of age with uveitis were eligible for inclusion. Demographics (age at first presentation, sex), ocular signs (affected eye segment, laterality, visual acuity; VA, Snellen, decimal, clinical course), and systemic finding were analysed. Frequencies and descriptive statistics were computed, non-parametric tests and odds ratio were applied for sample comparisons. Local ethics committee approved this study.
resultsData from 93 of 133 identified patients were available. 51% were female, mean age at first presentation was 12 years, 60% had bilateral disease. 68% were of non-infectious etiology. Most common identified etiology was toxoplasmosis (20%), followed by JIA (8%) and herpetic (8%). No associated infectious cause or systemic disease was found in 44% of the cases. Most presented with anterior uveitis (50%), followed by posterior (28%), intermediate (20%), and panuveitis (2%). 80% of anterior uveitis were non-infectious; 81% of posterior uveitis were infectious. Bilateral disease was strongly associated with non-infectious uveitis (93%), whereas unilateral disease was more likely to be of an infectious cause (70%); odds ratio = 31. Mean VA of affected eyes at first presentation was 0.79. VA was significantly worse in cases with infectious uveitis compared to non-infectious uveitis (p = 0.007). Nearly a third of affected eyes showed at least one complication. This did not differ between in non-infectious and infectious uveitis cases.
conclusionBilateral disease is strongly suggestive of non-infectious uveitis. Unilateral and posterior disease is suggestive of an infectious cause, with toxoplasmosis being the most often diagnosed cause of uveitis in this cohort. Knowledge of demography is important for specialists to target workup and introduce treatment.
