Optic chiasmal edema observed on T2-weighted MR images: a reversible finding in obstructive hydrocephalus.
Article in Japanese journal of radiology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 evaluate the clinical significance of optic chiasmal edema (OCE) observed in hydrocephalus. MATERIALS AND
methodsTwenty patients with obstructive hydrocephalus and eight patients with communicating hydrocephalus were recruited. We classified both groups into OCE-positive and negative subgroups on three-dimensional T2-weighted images. In the obstructive hydrocephalus group, the pre- and postoperative periventricular hyperintensity (PVH) grade, Evans index, and third ventricle diameter were compared between the subgroups. The visual disturbances were reviewed in the medical records.
resultsEleven obstructive hydrocephalus patients (55 %) had OCE, while none of communicating hydrocephalus patients did. OCE was improved in all patients postoperatively. Preoperative PVH grade was significantly higher in the OCE-positive subgroup (p < 0.01). There were no statistically significant differences in the other indices. Visual disturbances were observed in two OCE-negative patients alone.
conclusionOCE is a reversible finding frequently observed in obstructive hydrocephalus and may not be associated with visual disturbances.
