1 · What the graph read from it

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.

2 · The registry

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

Aim: Prehospital extracorporeal cardiopulmonary resuscitation (ECPR) has been proposed to reduce delays in ECPR delivery in refractory out-of-hospital cardiac arrests (OHCA) and improve outcomes. Our aim was to synthesize the literature on outcomes of prehospital ECPR in OHCA, focusing on low-flow times (emergency call to extracorporeal blood flow) and survival with good neurological function, comparing them to in-hospital ECPR when possible. Methods: We conducted a systematic review and Results: Eight cohort studies involving 305 patients (84% male, mean age 57) were included. Survival with good neurological function was 25% (95%CI: 17-35%). Mean low-flow time was 59 min (95%CI: 46-72). Meta-regression showed a significant inverse association between low-flow time and good neurological outcomes (β = -0.0271, 95%CI: -0.0536 to -0.0006; p = 0.045). Compared to in-hospital ECPR, prehospital ECPR showed no significant difference in survival (RR 1.23, 95%CI: 0.35-4.38) but was associated with significantly shorter low-flow times (mean difference -30 min, 95%CI: -44 to -16). Conclusion: Prehospital ECPR is associated with a 25% rate of survival with good neurological function. Shorter low-flow times were associated with improved outcomes.
