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

BACKGROUND AND

objectivesThe outcomes and characteristics of out-of-hospital cardiac arrest (OHCA) vary across geographic regions. The etiologies and prognoses of OHCA in Asian populations remain less established. This study aimed to investigate the etiologies and clinical characteristics of patients successfully resuscitated after OHCA and to identify predictors of survival outcomes.

methodsData were extracted from a South Korean multicenter prospective registry of OHCA that included 64 tertiary hospitals from 2015 to 2018 (n=7,577). The primary outcome was in-hospital mortality, and the secondary outcome was a Cerebral Performance Category (CPC) score of grade 1 at discharge.

resultsOf the 7,577 patients, 2,066 achieved return of spontaneous circulation (ROSC) and were hospitalized. A total of 915 (44.2%) presented with ventricular arrhythmia (VA) as their initial rhythm or on admission. The leading cause was obstructive coronary artery disease (n=413; 20.0%). Sudden unexplained death syndrome (SUDS) accounted for 67.5% of survivors and was significantly less common in patients with VA (82.7% vs. 48.3%, p<0.001). VA was an independent predictor of in-hospital mortality (adjusted hazard ratio, 0.774; 95% confidence interval [CI], 0.633-0.946; p=0.012) and the grade-1 CPC score at discharge (odds ratio, 2.822; 95% CI, 1.909-4.172; p<0.001). Other predictors of in-hospital mortality included age, diabetes mellitus, witnessed cardiac arrest, ROSC on arrival, total arrest time, alertness on admission, extracorporeal membrane oxygenation use, targeted temperature management, and coronary reperfusion.

conclusionsSUDS was common in patients with ROSC after OHCA. VA was independently associated with favorable survival outcomes at discharge. Prompt clinical intervention may improve clinical outcomes in patients with OHCA, particularly those with VA.
