Normative optical coherence tomography-based measurements and classification of optic nerve head parameters in adult Congolese subjects.
Article in Frontiers in 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
Background: Normative data on optic nerve head (ONH) topographic measurements are scarce among black people residing in Africa. Such measurements obtained with imaging modalities such as optical coherence tomography (OCT) are crucial for the diagnosis and management of optic nerve diseases, particularly glaucoma. They assist clinicians in identifying deviations that may indicate disease or abnormalities. The aim of this study was to determine normal reference values of ONH topographic measurements in a Congolese adult population using OCT. Methods: Hospital-based cross-sectional observational study of 263 healthy adult subjects (18-76 years) who were scanned with a Topcon 3D OCT-2000 device using the optic disc scan pattern. The 2.5 Results: The median (IQR) was 2.70 (0.92) mm Conclusion: This study provides population-specific normative data describing ONH morphology in healthy Congolese adults, addressing a critical gap for African populations that remain underrepresented in ocular imaging research. These ONH measurements were significantly greater than found in other populations. They may be used for diagnostic reliability and classification of Congolese subjects.
