Association Between the Duration of Elevated Perfusion Pressure and Neurological Outcomes in Out-of-Hospital Cardiac Arrest Survivors.
Article in Reviews in cardiovascular medicine, 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
Background: The association between elevated perfusion pressure and neurological outcomes in out-of-hospital cardiac arrest (OHCA) survivors remains unclear. Specifically, to our knowledge, no studies have currently investigated whether the duration of elevated perfusion pressure influences neurological prognosis following OHCA. Thus, this study aimed to examine the association between the duration of a mean arterial pressure (MAP) >80 mmHg during the first 48 hours after return of spontaneous circulation (ROSC) and neurological outcomes in OHCA survivors. Methods: This observational study included adult patients (≥18 years) with OHCA treated between January 2019 and May 2021. The cumulative duration of a MAP >80 mmHg was recorded during the 0-24, 25-48, and 0-48 hour intervals following ROSC. The primary outcome was the neurological status at 6 months, with good outcomes defined as Cerebral Performance Category (CPC) scores of 1 or 2. Results: Among the 468 patients with OHCA, 132 (28.2%) achieved good neurological outcomes. The duration of a MAP >80 mmHg over 0-48 hours was significantly longer in the good outcome group compared with the poor outcome group (35 (26-42) vs. 28 (16-39) hours; Conclusions: The duration of a MAP >80 mmHg during the 0-48 and 25-48 hour periods after ROSC was associated with good neurological outcomes at six months in OHCA survivors.
