Investigation of the effect of carnitine on cerebral vasospasm in experimental subarachnoid hemorrhage model.
Article in Scientific reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
The vasospasm, which develops after subarachnoid hemorrhage (SAH), is an unenlightened table in terms of etiology and results. It is usually associated with decreased perfusion, which is associated with decreased blood flow distal to the affected artery and can be demonstrated radiologically. Acetyl-L-carnitine (ALCAR) can be found in brain tissue and easily crosses the blood-brain barrier. Therefore, in this study, we aimed to investigate the therapeutic efficacy of ALCAR, which is an effective antioxidant amine, on vasospasm development after experimental SAH. In our study, 35 adults male Wistar RATs weighing between 235-250 g were used. These RATs were divided into five groups with n = 7. Group 1 Control group, Group 2 SAH + SF (carrier solution), Group 3 SAH + ALCAR 50 mg\kg intraperitoneally, Group 4 SAH + ALCAR 100 mg\kg intraperitoneally and Group 5 SAH. Subarachnoid hemorrhage was induced by giving autologous arterial blood to the cisterna magna of the animals in groups 2, 3, 4, and 5. At 0.-12.- 24.- 36.- 48.- 60. and 72. h, Group 2 was injected with SF, Group 3 with intraperitoneally ALCAR 50 mg\kg, and Group 4 with intraperitoneally ALCAR 100 mg\kg, respectively. Following perfusion and fixation, the animals were subjected to a wide craniectomy, and the brain, cerebellum, and brain stems were removed globally. Then, sections were taken from the basilar arteries of all animals and photographed at 40X magnification. Basilar artery lumen cross-sectional areas, basilar artery areas, and wall thicknesses were measured from these sections. The basilar artery lumen cross-sectional area was found to be significantly larger in the groups in which SAH was formed and ALCAR 50 mg\kg and ALCAR 100 mg\kg were given compared to the group with only SAH and SAH + SF (p = 0.0408). Basilar artery wall thickness increased in all groups except the control group (p < 0.05). In light of all these findings, it was concluded in our study that Carnitine was effective in the resolution of vasospasm in the experimental SAH model.
