Critical limits for early detection of glaucoma, the Uppsala Glaucoma Detection Study (UGDS).
Article in International 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
purposeThe current study aimed to optimize the measurement design for each quantity of interest, determine critical limits for clinically distinguishing glaucoma-suspect eyes from non-suspect eyes in the UGDS using the optimized design, and compare the efficiency of the measured quantities in estimating sensitivity
methodsData from non-glaucoma suspect eyes in the UGDS were analyzed for age and sex dependence, sources of variation, frequency distribution, and assessment of critical limits for glaucoma detection. Critical limit was defined as the extreme 95% confidence limit for the 95% one-sided tolerance. Intraocular pressure (IOP) and visual field contract sensitivity (Mean Deviation, MD), linear cup-to-disc ratio (C/D-linear), neuro-retinal rim area (NRA), nerve fiber layer thickness (cpRNFLT-Global and GDx-TSNIT) were examined
resultsAnalysis revealed no significant age or sex dependence for the measured quantities. Variability among subjects was found to dominate, affecting the precision of measurements. Frequency distributions approximated normal distributions, enabling the estimation of tolerance limits for critical assessment. The critical limits to distinguish pathological from non-pathological were estimated as 22 mmHg, -3.7 dB, 0.84, 0.6 mm
