The Signature of Serum Modified Nucleosides in Uveitis.
Article in Investigative ophthalmology & visual science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Purpose: This study aims to evaluate the metabolism of serum-modified nucleosides in uveitis by using liquid chromatography-tandem mass spectrometry (LC-MS) and to develop potential diagnostic biomarkers for uveitis. Methods: Forty-two patients with different subtypes of uveitis (idiopathic uveitis, Vogt-Koyanagi-Harada [VKH] disease, and ankylosing spondylitis [AS]) and 32 healthy controls were recruited in this retrospective case-control study. The concentrations of 23 modified nucleosides in patient serum were quantified by LC-MS. The data was statistically analyzed with SPSS and GraphPad Prism. Results: The data revealed that 13 out of 23 modified nucleosides (m6A, m1A, m6Am, Cm, ac4C, Gm, m1G, m2G, m2,2G, Um, m3U, m5U, and m5Um) effectively showed quantifiable chromatographic peaks. The statistical results indicated that there were extremely significant differences for m2G, Gm, Cm, and m1G between healthy controls and uveitis patients. The differences for Gm, m6A,and m5U were able to further assort idiopathic uveitis and uveitis with systemic inflammation including VKH and AS. Interestingly, each specific subtype of uveitis is characterized by its signature combination of serum-modified nucleotides comparing with healthy controls. Conclusions: This study revealed that the metabolism of serum-modified nucleosides in uveitis patients display significant differences from healthy controls. The signature combination of serum modified nucleotides for each subtype of uveitis may be applied for the potential diagnosis of uveitis.
