Can interferon-inducible gene expression guide treatment? A prospective study in QuantiFERON-positive uveitis with undetermined cause.

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
purposeThe purpose of this study was to evaluate the utility of baseline interferon (IFN)-inducible gene expression as a prognostic biomarker for Anti-tubercular therapy (ATT) response in patients with undetermined cause of uveitis who tested positive for QuantiFERON-TB Gold (QFT-positive uveitis).
methodsThis prospective cohort study included 17 QFT-positive uveitis patients at a tertiary uveitis center in Indonesia. Baseline and week 2 peripheral blood transcripts were evaluated through real time-quantitative polymerase chain reaction to assess the expression of 10 IFN-inducible genes (IRF7, IFIT2, STAT1, IL1B, MyD88, TLR8, FCGR1B, GBP1, UBE2L6, and SERPING1). Patients were stratified into clusters based on gene expression patterns. The primary outcome was complete resolution of uveitis at 6 months.
resultsHierarchical clustering revealed two distinct groups. Patients with higher baseline expression of IFN genes (Cluster 2) were more likely to achieve complete uveitis resolution after ATT compared to those with lower expression levels (Cluster 1) (80% vs. 43%). Using a previously established IFN gene signature score (IGSS) cutoff (≥5.61), 82% of high-scoring patients showed complete resolution, compared to only 33% in the low-scoring group (
conclusionBaseline, but not week 2, peripheral blood IFN-inducible gene expression may serve as a prognostic biomarker for stratifying QFT-positive uveitis patients through prediction of their response to treatment. Patients with higher baseline IGSS are more likely to require ATT to achieve uveitis resolution at 6-month follow-up.
