Corvis ST parameters in eyes with primary angle-closure glaucoma: a retrospective cross-sectional study using propensity score matching.
Article in BMC ophthalmology, 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
backgroundTo evaluate differences in Corvis ST tonometry (CST) parameters between healthy eyes and eyes with primary angle-closure glaucoma (PACG).
methodsWe retrospectively analyzed CST parameters of 24 healthy eyes and 24 eyes with PACG after 1:1 propensity score matching based on age, sex, axial length, intraocular pressure, and central corneal thickness. Differences in 12 CST parameters were evaluated using linear mixed-effects models, with group as a fixed effect and subject ID as a random intercept to account for inter-eye correlation. The models were adjusted for age, sex, axial length, intraocular pressure, and central corneal thickness. Multiple comparisons across parameters were controlled using the Benjamini–Hochberg false discovery rate procedure.
resultsCompared with healthy eyes, eyes with PACG exhibited greater A1 deformation amplitude and a shorter A2 time.
conclusionsCompared with healthy eyes, eyes with PACG showed differences in selected CST parameters, specifically greater A1 deformation amplitude and shorter A2 time. These findings may indicate altered corneal dynamic response behavior in PACG.
