Observational Study of Words Used by Emergency Callers and Their Impact on the Recognition of an Out-Of-Hospital Cardiopulmonary Arrest by the Medical Dispatcher.
Observational study in Arquivos brasileiros de cardiologia, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundSurvival of victims of out-of-hospital cardiopulmonary arrest (CA) is related to the time and quality of cardiopulmonary resuscitation (CPR).1 Considering that most CAs occur outside the hospital setting, it is evident that the early recognition of this condition is the cornerstone of the chain of survival. Current literature on the theme is still scarce.
objectivesTo analyze categories and subcategories of words and expressions spontaneously used by laypeople during emergency calls for CA and their relationship with the recognition of this event by the medical dispatcher.
methodsThis was a cross-sectional study, with analysis of calls made by laypeople due to suspected CA to emergency medical services in Brazil. The expressions used were classified into six categories and 31 subcategories. Univariate and multivariate models were used to assess the strength of the association of categories and subcategories of words and expressions with the presumption of CA. The level of significance was set at 5%. Results: A total of 284 calls were included, and after applying the inclusion criteria, 101 calls were analyzed. The categories "cardiovascular/perfusion status" (p=0.019) and "general status" (p=0.011) were identified as confounding factors for the recognition of CA, and the subcategories "breathing difficulty" (p=0.023), "verbal unresponsiveness" (p=0.034), "facial coloration" (p=0.068) and "feeling unwell" (p=0.013) were also considered as confounders. On the other hand, the subcategories "not breathing" (p=0.010); "spatial position" (p=0.016), and "cardiovascular emergencies" (p=0.045) were identified as facilitating factors for the recognition of CA.
conclusionCategories and subcategories of expressions used by emergency callers for CA can influence the timely recognition of this condition by the medical dispatcher.
