Ocularultrasound versus SD-OCT in early papilledema differentiation.
Article in Bioinformation, 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
Differentiating early papilledema from pseudopapilledema remains a considerable diagnostic challenge in neuro-ophthalmology due the risks surrounding unnecessary neuroimaging or under-treatment of elevated ICP. Therefore, it is of interest to study of ocular ultrasonography and SD-OCT was carried out in 60 patients with elevation of the optic disc from September 2022 to February 2024. Papilledema was defined as optic nerve sheath diameter >3.3 mm, a positive 30°C test and crescent sign while pseudopapilledema was often associated with hidden disc drusen. SD-OCT had higher sensitivity than ultrasonographic examination (86.7% vs 81.7%) and eyes with papilledema showed thicker peripapillary RNFL, increased ONH volume, decreased GCIPL, enlargement of the blind spot or reduced contrast sensitivity and colour desaturation. The two modalities complement each other - SD-OCT provides quantification and allows differentiation whereas ultrasonography can show anatomical biomarkers, together allowing the early detection of intracranial hypertension as well as avoiding invasive investigations in cases of pseudopapilledema.
