The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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.

Abstract
In this study, we investigated the role of vitamin D3 (VitD3) on endogenous osteopontin (OPN), a neuroprotective glycoprotein, after subarachnoid hemorrhage (SAH). The endovascular perforation SAH model in Sprague-Dawley rats was used to study the effect of intranasal VitD3 (30 ng/kg) before (Pre-SAH + VitD3) and after (Post-SAH + VitD3) subarachnoid hemorrhage. Vitamin D3 (30, 60, 120 ng/kg/day) increased more than one fold endogenous OPN expression in astrocytes and endothelial cells of rat brain. Vitamin D3 significantly decreased brain edema and Evans blue extravasation. In addition, neurobehavioral scores were significantly higher in Pre-SAH + VitD3, but partly higher in Post-SAH + VitD3, group compared with SAH group. These protective effects of vitamin D3 were completely attenuated by intracerebroventricular injection of transcription inhibitor Actinomycin D and significantly inhibited by small interfering ribonucleic acid (siRNA) for vitamin D receptor and OPN in Pre-SAH + VitD3 rats. OPN expression was significantly higher in Pre-SAH + VitD3 rats, specifically A and C, but not B, isomers were upregulated in the astrocytes, leading to CD44 splicing, and P-gp glycosylation in brain endothelial cells. The results show that intranasal vitamin D3 attenuates blood-brain barrier (BBB) disruption through endogenous upregulation of OPN and subsequent CD44 and P-gp glycosylation signals in brain endothelial cells. Furthermore, this study identifies a novel strategy for the cost-effective management of subarachnoid hemorrhage.
