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
aimTo assess the impact of time to return of spontaneous circulation (ROSC) on early in-hospital neurological function and long-term survival in survivors after out-of-hospital cardiac arrest (OHCA).
methodsThis retrospective cohort study included survivors of OHCA admitted to the cardiology ward at Aarhus University Hospital. Patients were included from June 2020 to February 2024 and data were collected through review of medical records. Primary outcome was neurological function, and patients were stratified by modified Rankin Scale (mRS) at hospital discharge: good neurological outcome (mRS 0-2) and poor neurological outcome (mRS 3-6). Secondary outcomes were cognitive function assessed with Montreal Cognitive Assessment (MoCA) at hospital discharge and 180-day survival.
resultsIn total, 321 patients were included, of which 232 (72%) had good neurological outcome and 89 (28%) had poor neurological outcome. Every 5-min increase in time to ROSC was associated with decreased odds of good neurological outcome (OR 0.88, 95% CI 0.81-0.95, p < 0.0001). This association remained significant after adjusting for age and primary rhythm (OR
conclusionIn initial OHCA survivors transferred to the cardiology ward, increased time to ROSC was independently associated with decreased odds of good neurological function at hospital discharge, even after adjusting for age and primary rhythm. The majority of patients had good neurological function at hospital discharge. In this population time to ROSC was not associated with mortality.
