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

aimThe present study aimed to describe the prevalence, prognosis and annual trends of extracorporeal cardiopulmonary resuscitation (ECPR) for out-of-hospital cardiac arrest (OHCA) patients, using a nationwide inpatient database in Japan.

methodsThis was a nationwide retrospective cohort study, using the Japanese Diagnosis Procedure Combination inpatient database. We included OHCA patients registered in the database from July 2010 to March 2017 and analyzed the annual prevalence of OHCA patients who received ECPR. The outcomes included survival to hospital discharge and survival with favorable neurologic outcome at hospital discharge. The annual trends on the outcomes were also analyzed.

resultsWe identified 217,907 eligible patients. OHCA patients were divided into patients with ECPR (n = 5,612) and conventional CPR (n = 212,295). The prevalence of ECPR performed in OHCA patients was 2.6%. ECPR prevalence significantly increased from 2.1% in 2010 to 3.0% in 2016 (

conclusionsThe annual prevalence of ECPR significantly increased from 2010 to 2016. Improvements in overall survival to hospital discharge were noted for ECPR in OHCA patients and there was a trend in the tendency for ECPR patients discharged from the hospital to have favorable neurologic outcomes.
