Dual-dispatch protocols and return of spontaneous circulation in patients with out-of-hospital cardiac arrest: a nationwide observational study.
Article in Clinical and experimental emergency medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveThe Korean National Fire Agency conducted a pilot project examining Advanced Life Support (ALS) protocols, including epinephrine administration, to improve survival among patients suffering out-of-hospital cardiac arrest (OHCA). In this study, we aimed to evaluate the effects of the Korean National Fire Agency ALS protocol on prehospital return of spontaneous circulation (ROSC) in patients with OHCA.
methodsThis study included patients with adult-presumed cardiac arrest between January and December 2020. The main factor of interest was ambulance type according to ALS protocol, which was divided into dedicated ALS ambulance (DA), smartphone-based ALS ambulance (SALS), and non-DA, and the main analysis factor was prehospital ROSC. Multivariate logistic regression analysis was performed.
resultsDuring the study period, a total of 18,031 adult patients with OHCA was treated by the emergency medical services, including 7,520 DAs (41.71%), 2,622 SALSs (14.54%), and 7,889 non-DAs (43.75%). The prehospital ROSC ratio was 13.19% for DA, 11.17% for SALS, and 7.91% for non-DA (P<0.01). Compared with that of the DA group, the odds ratios (95% confidence interval) for prehospital ROSC ratio were 0.97 (0.82-1.15) in the SALS group and 0.57 (0.50-0.65) in the non-DA group. The prehospital ROSC ratio of the DA group was higher than those of the non-DA group and the SALS group.
conclusionALS protocol intervention was associated with prehospital ROSC rates. Therefore, continuous efforts to promote systemic implementation of the ALS protocol to improve OHCA outcomes are necessary.
