Corneal astigmatism agreement between a swept-source ocular coherence tomography and Scheimpflug-Placido based optical biometers.
Article in International ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeThis prospective and comparative study assesses the agreement of anterior, posterior, and total corneal astigmatism measurements between swept-source optical coherence tomography (Anterion) and Scheimpflug cameras, Placido disc, and OCT-based tomography (Galilei G6).
methodsA total of 59 eyes of 59 patients were assessed using two optical biometers. Anterior, posterior, and total keratometry measurements were obtained, and flat (K1), steep (K2), astigmatic power, and J vectors (J
resultsStatistically significant differences were found for flat keratometry measurements of anterior corneal power (Galilei G6: 43.41 ± 1.78; Anterion: 43.32 ± 1.73) and total corneal power (Galilei G6: 42.41 ± 1.85; Anterion: 42.84 ± 1.81), as well as for steep keratometry of posterior corneal power (Galilei G6: - 6.41 ± 0.38; Anterion: - 6.31 ± 0.30) and total corneal power (Galilei G6: 43.69 ± 1.89; Anterion: 43.91 ± 1.89) (p < .05). In contrast, no statistically significant differences were found for the mean power vector components comparison between the devices. Agreement analysis showed significant proportional bias for cylindrical power and vector components (J
conclusionAnterior, posterior, and total astigmatism measurements between the Anterion and Galilei G6 are not interchangeable.
