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

backgroundExtracorporeal cardiopulmonary resuscitation (ECPR) is increasingly used for adults with cardiac arrest (CA) refractory to Advanced Cardiovascular Life Support (ACLS). Concerns exist that adding ECPR could worsen health inequities, defined as differences in health outcomes that are unfair or unjust. Current guidelines do not explicitly address this issue. This study narratively reviews the latest evidence on ECPR, focusing on its implications for health equity and derives a health equity tool that may serve as a basis of comparison for resuscitation sciences.

methodsWe searched the American Heart Association (AHA) and International Liaison Committee on Resuscitation (ILCOR) websites for the latest ACLS guidelines and scientific summaries on ECPR for CA and identified randomized controlled trials (RCTs) and observational studies. We identified population and individual characteristics associated with inequities based on the literature and expert opinion. These characteristics were used as a health equity tool to assess: differences in baseline risk, population exclusion and trial representation in studies, outcome analyses, and implementation barriers. We used the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) Evidence to Decision (EtD) framework to evaluate ECPR's impact on health equity.

resultsFour RCTs involving 435 patients were conducted in the (2/4) USA, (1/4) Czech Republic, and (1/4) Netherlands. We identified thirteen characteristics associated with health inequities. All trials took place in urban, high-resourced hospitals and excluded older adults (60-75+ years). Across all RCTs, women were under-represented, and in the two USA-based trials, Black individuals were under-represented. There was no difference in baseline rate of survival with minimal or no neurologic impairment between sexes, but an observed trend favoring younger patients (<65). One trial's subgroup analysis showed no significant differences in ECPR effectiveness by sex or age. We noted that implementing ECPR for out-of-hospital CA faces challenges due to demographic variability, differences in emergency services, access to existing ECPR programs, and limited implementation outside urban areas.

conclusionsA health equity tool based on axes of health inequities for resuscitation identified that health equity is reduced with the use of ECPR for CA. Mitigation strategies should involve evaluating demographics, health equity measures, outcomes and ensuring equitable access to ECPR across catchment areas before and after implementation.
