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 remains a major public health concern in Thailand, where pre-hospital care and survival outcomes vary widely across regions. Furthermore, national-level data remains sparse and fragmented. Methods: This retrospective, multicenter cohort study analyzed adult out-of-hospital cardiac arrest cases from 2017 to 2023 using standardized data from the Pan-Asian Resuscitation Outcomes Study registry. Patients were included if they received emergency medical services in the field, regardless of whether they were transported to hospital or not. The study involved three hospitals representing regional, suburban-capital, and urban-capital settings. The primary outcome was 30-day survival. A modified Poisson regression with robust error variance was performed to identify pre-hospital factors associated with survival. Results: Among 2259 eligible cases, 30-day survival was low, with notable variation across hospital settings. Bystander cardiopulmonary resuscitation was most frequent in the suburban-capital hospital (47.2%) and lowest in the regional hospital (23.7%). Family members were the most common providers of bystander cardiopulmonary resuscitation across all sites, though healthcare professionals were more frequently involved in the regional hospital. Multivariable analysis showed that bystander cardiopulmonary resuscitation and shorter emergency medical services response time were significantly associated with improved survival, while advanced airway management and transport time were not. Conclusion: This study confirmed the importance of bystander cardiopulmonary resuscitation and services response time in patient survival in Thailand and highlighted regional disparities. A coordinated national registry is urgently needed for targeted improvements. Lack of standardized and comprehensive data, especially neurologic outcomes and long-term survival, hinders performance evaluation and evidence-based reform.
