Impact of coma duration on functional outcomes at discharge and long-term survival after cardiac arrest.
Article in Resuscitation, 2025. 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
introductionAwakening from coma is crucial for survivors of cardiac arrest, though coma duration is variable. We tested the association of coma duration with short-term functional recovery and long-term survival after cardiac arrest.
methodsIn this retrospective cohort study, we identified post-arrest patients who were comatose on presentation but awakened during hospitalization. We recorded demographics, arrest characteristics, days from arrest to awakening, and modified Rankin Scale (mRS) at hospital discharge. We compared discharge mRS between patients with short and long coma duration dichotomized at its median, 3, and 6 days. We compared long-term survival between patients with short and long coma duration who survived to hospital discharge. Finally, we used Cox regression to quantify the independent association of coma duration with survival after adjusting for patient and arrest characteristics.
resultsWe included 979 subjects with median coma duration 2 [IQR 1-4] days. Shorter coma duration was associated with a higher proportion of patients with discharge mRS ≤ 3 (p < 0.001). We observed 742 subjects who survived to discharge for 3,136 person-years and found no difference in long-term survival between short and long coma durations (p = 0.86). Coma duration was not associated with hazard of death (HR 1.00, 95 %CI 0.97-1.03) after adjusting for age, location of arrest, Charlson Comorbidity Index, and discharge mRS.
conclusionsShorter coma duration was associated with better functional outcome at discharge, but not with long-term survival.
