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.
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: The Out-of-hospital cardiac arrest (OHCA) remains a major public health challenge worldwide, with survival outcomes heavily influenced by early intervention. The presence of an initial shockable rhythm significantly increases the likelihood of survival when combined with timely cardiopulmonary resuscitation (CPR) and defibrillation. Objective: To analyze patient outcomes and the incidence of bystander and dispatch-guided CPR in cases of OHCA with an initial shockable rhythm treated by physician-led emergency medical teams in Bosnia and Herzegovina. Methods: Data for this study were collected over a 5-year period, from January 2019 to September 2023, using the Utstein protocol. Hospital records were analyzed to determine patient outcomes, with a focus on the 30-day survival rate and favorable neurological outcomes. Instances of dispatch-guided and bystander CPR were recorded for each case based on available patient records. Results: In this study, 1,020 patients were included, with 151 cases (14.8%) having an initial shockable rhythm, of which 14.3% of males and 4.4% of females achieved return of spontaneous circulation (ROSC). ROSC rates varied by year, with the highest in 2019 (20.4%) and 2022 (17.9%). Thirty-day survival with a good neurological outcome was observed in a small percentage of cases. The initial shockable rhythm was found to be statistically significant (p<0.001) for achieving a good neurological outcome after 30 days. Dispatch-guided CPR was attempted in 12.9% of cases, with success in 1.9%. Bystander CPR was performed in 1.4% of cases, and only one case involved the use of an automated external defibrillator (AED). The median response time for successful resuscitations was 2 minutes, while for unsuccessful resuscitations, it was 6 minutes. The findings emphasize the role of age, initial rhythm, and response time in determining outcomes for OHCA patients. Conclusion: The promising survival rate of OHCA patients, despite limited bystander CPR, highlights the impact of short response times and skilled physician-led teams, underscoring the need for public education and a unified registry to address gaps and better understand OHCA epidemiology in Bosnia and Herzegovina.
