Risk factors for tube exposure following Baerveldt glaucoma implantation and overlying tissue thickness assessed by anterior segment optical coherence tomography.

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
purposeWe identified clinical factors associated with tube exposure following Baerveldt glaucoma implantation (BGI) and used anterior segment optical coherence tomography (AS-OCT) to assess postoperative tissue thickness over the tube. STUDY
designRetrospective, single-center cohort study.
methodsIn this single-center retrospective cohort study, 405 eyes underwent BGI (BG101-350) with preserved scleral patch grafts between October 2014 and December 2022. Tube exposure was documented through clinical records and slit-lamp examination. Risk factors were evaluated using Firth's penalized logistic regression. Overlying tissue thickness at 1 year postoperatively was measured via AS-OCT, and its association with clinical variables was analyzed using linear regression.
resultsThe mean follow-up was 630.7 days, and tube exposure occurred in 12 eyes (2.96%). Neovascular glaucoma (NVG) (odds ratio [OR] 5.03, p = 0.033) and anterior chamber (AC) tube insertion (OR 6.07, p = 0.017) were independently associated with exposure. Overlying tissue was significantly thinner with AC insertion compared with ciliary sulcus or pars plana placement (Kruskal-Wallis with Bonferroni-adjusted Dunn's tests; AC vs sulcus, p = 0.039; AC vs pars plana, p < 0.001). Among eyes with AC insertion, prior micropulse transscleral cyclophotocoagulation (MP-CPC) was associated with greater tissue thickness (estimate 0.173; p = 0.032).
conclusionAC insertion and NVG were associated with an increased risk of tube exposure after BGI. AS-OCT revealed thinner tissue over AC-placed tubes, providing a structural basis for this risk. Avoiding AC insertion may reduce exposure; the observed association between prior MP-CPC and thicker tissue requires prospective validation.
