Subarachnoid Hemorrhage after Resuscitation from Cardiopulmonary Arrest: A Comparison of Survivor and Dead Cases.
Article in Journal of neuroendovascular therapy, 2025. 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
Objective: The prognosis of patients with subarachnoid hemorrhage (SAH) who also develop cardiopulmonary arrest (CPA) is highly unfavorable, and hence they are often not aggressively treated. Presently, the therapeutic indications and factors that affect the prognosis of patients who experienced CPA remain unclear. Therefore, we analyzed SAH patients who experienced CPA, comparing the characteristics of the patients who survived with those who did not. Methods: The 36 patients were divided into the survivor group (n = 4) and the dead group (n = 32). The patient's age, sex, location of the aneurysm, the presence of intracranial hematoma, duration of cardiopulmonary resuscitation (CPR), the presence/absence of bystanders, initial electrocardiogram waveform, recovery of brainstem reflexes with motor response, and administration of vasopressors were compared between the 2 groups. Results: There were no significant differences in age, sex, location of the aneurysm, and presence of intracranial hematoma between the 2 groups. More than 90% of patients in the dead group had a non-shockable rhythm on the initial electrocardiogram waveform. The duration of CPR in the survivor group tended to be shorter than that in the dead group. Bystander CPR was performed on 14 patients, including all 4 of the survivors. All patients in the survivor group achieved recovery of brainstem reflexes with motor response. In the survivor group, all patients either did not need or only transiently needed the administration of vasopressors after the return of spontaneous circulation (ROSC). Conclusion: Our analysis suggested the following as favorable prognostic factors in SAH patients with CPA: shockable arrhythmia on the initial electrocardiogram waveform, young age, bystander CPR, a short time from CPA to ROSC, recovery of brainstem reflexes with a motor response, and no or transient use of vasopressors. Our results indicate that aggressive treatment may be indicated in SAH patients with CPA who have stable vitals and show improvements in neurological symptoms.
