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: Out-of-hospital cardiac arrest (OHCA) is a critical challenge for public health, with wide variation in epidemiology and outcomes in different countries and regions. We aimed to describe the epidemiology and outcomes for OHCA in Zhejiang, China based on Electronic Medical Record Surveillance. Methods: This retrospective study using the Zhejiang Emergency Command Center Electronic Medical Record System in Zhejiang Province, China. We included OHCA cases with non-traumatic, aged 18 years and above and had resuscitation attempted by emergency medical services (EMS). All data were collected and reported using the Utstein template. The primary outcomes were survival to discharge or 30th day, the secondary outcomes were survival with favorable neurological outcomes. Results: 6923 non-traumatic OHCA patients with aged 18 and above were identified. The OHCA incidence assessed by EMS was 37.6 per 100,000 population. The median age was 68 (54-79) years, with more than half of patients aged 65 or older. 4860 (70.2%) were male, 5033 (72.7%) had cardiac arrest at home. 2889 (41.7%) patients had bystander cardiopulmonary resuscitation (CPR). Among 6923 non-traumatic, 608 (8.8%) patients had shockable rhythm, 497 (7.2%) patients achieved return of spontaneous circulation (ROSC), 82 (1.2%) patients survived to hospital discharge. Under 65 years of age who received bystander CPR, 173 (12.1%) patients achieved ROSC, 43 (3.0%) patients survived to hospital discharge. Conclusion: The survival after OHCA in Zhejiang Province is unsatisfactory, especially for those above 65 years patients. Electronic Medical Record Surveillance can assist the implementation of the chain of survival to improve outcomes.
