Respiratory Drive and Survival in Comatose Out-of-Hospital Post-Cardiac Arrest Patients.
Article in Open access emergency medicine : OAEM, 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
Purpose: This study aimed to explore alterations in respiratory drive in comatose patients after out-of-hospital cardiac arrest (OHCA) and their association with survival outcomes. Patients and Methods: A prospective cohort study was conducted on comatose patients with OHCA who were admitted between October 2022 and October 2024. Patients were followed until their discharge from the hospital and subsequently categorized into survivors and non-survivors. Respiratory drive was evaluated using P0.1, representing the airway occlusion pressure measured within the first 100 ms of inspiration, as displayed on the ventilator. Measurements were collected together with additional parameters at 24, 48, and 72 h following admission. Results: The analysis involved 30 patients, with an in-hospital mortality rate of 53.3%. Over the 72-h observation period, P0.1 values were greater in survivors than in non-survivors; however, this difference was not statistically significant. During the first 24 h, survivors demonstrated significantly lower tidal volumes per predicted body weight (P = 0.034). P0.1 values ranging from 1.5 to 3.5 cmH Conclusion: A trend toward elevated P0.1 levels in survivors was observed. P0.1 values within the range of 1.5-3.5 cmH
