Concordance of Corneal Tomographic Measurements Obtained via Swept-Source Optical Coherence Tomography Versus Scheimpflug Tomography.
Article in Bioengineering (Basel, Switzerland), 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
purposeTo compare concordance of corneal tomographic measurements obtained using Anterion versus Pentacam HR.
settingOutpatient ophthalmology clinic.
designRetrospective cross-sectional study.
methodsEyes without corneal abnormalities underwent tomography using the Anterion Cornea App and Pentacam HR. Measurements included anterior keratometry (K1, K2, ΔK, average K, K
resultsA total of 64 eyes of 41 patients underwent corneal tomography with both devices. Anterion and Pentacam HR showed strong linear correlations for all measurements (ρ > 0.700), with concordance ranging from satisfactory to excellent (CCC 0.704-0.981). No statistically significant mean inter-device differences were found for anterior K1 (0.01 diopters [D],
conclusionsAnterion and Pentacam HR showed satisfactory-to-excellent measurement concordance, with negligible mean inter-device biases for most anterior keratometry measurements and anterior astigmatism vectors. However, individual-eye differences could approach 0.49-0.61 D for anterior keratometry and exceed 20 μm for pachymetry. These differences may become relevant in borderline cases and during longitudinal disease monitoring, warranting parameter-specific caution.
