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
objectiveThis study aims to anatomically define and clinically evaluate the subchiasmatic-preinfundibular space (SCPIS) as an alternative surgical space for clipping contralateral ICA C7-segment aneurysms, by comparing its outcomes with those of the standard prechiasmatic space (PCS) and contralateral opticocarotid space (OCS).
methodsBasic Research: Five cadaveric heads were dissected via the pterional approach. Contralateral ICA exposure was measured through three spaces- PCS, contralateral OCS), and SCPIS-before and after anterior clinoid process (ACP) drilling. Clinical Research: A retrospective analysis of 53 patients with multiple intracranial aneurysms (MIAs) treated via unilateral craniotomy compared outcomes across three groups: SCPIS (Group 1), PCS (Group 2), and contralateral OCS (Group 3). Postoperative aneurysm occlusion rates, complications, discharge mRS scores, and 6-month neurological deficits were assessed.
resultsThe lengths of the contralateral ICA exposure increased significantly post-ACP drilling: PCS (5.62 ± 0.91 mm vs. 7.11 ± 0.84 mm, p < 0.001), contralateral OCS (4.44 ± 2.33 mm vs. 6.03 ± 2.30 mm, p = 0.001), and SCPIS (4.98 ± 1.91 mm vs. 6.67 ± 2.01 mm, p < 0.001). Significant increases were also observed in the lengths of the inferior border of the optic chiasm and/or optic nerves, the deep superior border of the diaphragma sellae, and the area of this space after ACP drilling (p < 0.05). SCPIS clipping showed no significant differences in hospitalization duration, complications (pneumonia, electrolyte disturbances, optic nerve injury, cerebral infarction), or discharge mRS scores (p > 0.05) compared to other approaches. The rate of complete angiographic occlusion of the contralateral aneurysms was comparable among the three groups (PCS: 88.6%, OCS: 90.9%, SCPIS: 85.7%; p = 0.92). Six-month neurological outcomes were satisfactory.
conclusionSCPIS is a viable alternative for contralateral ICA C7-segment aneurysm clipping. ACP drilling improves surgical access, and the approach is safe and effective.
