Epidemiological characteristics and factors associated with out-of-hospital cardiac arrest attended by bystanders before ambulance arrival.

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
backgroundThe aim of this study is to analyze the characteristics of out-of-hospital cardiac arrests based on whether patients received bystander resuscitation before ambulance arrival, and to describe the factors associated with resuscita-tion attempts by bystanders.
methodsA retrospective observational study was performed. Clinical data from cardiac arrest patients in the Basque Country (Spain) were collected over a period of five years. Epidemiological characteristics compared resuscitation started by bystanders with resuscitation carried out by ambulance caregivers. The relation between no resuscitation started by bystander and different exposure factors was explored by multiple logistic regression analysis.
resultsWe analyzed 3,278 cardiac arrests. Of them, 61.9?% were not attended by bystanders and this was associated with the absence of instructions from Emergency Centre (OR: 6.25, 95%CI: 5.15-7.58, p?<?0.001), home location (OR: 2.94, 95%CI: 2.48-3.48, p?<?0.001), unwitnessed cardiac arrest (OR: 1.56, 95%CI 1.28-1.89, p?<?0.001), victims of 65 years or older (OR: 1.48, 95%CI: 1.26-1.74, p?<?0.001) and suburban locations (OR: 1.29, 95%CI: 1.04-1.62, p?=?0.023).
conclusionThere are differences in cardiac arrests depending on whether they have been resuscitated by bystanders. These characteristics may influence the bystander's decision to initiate resuscitation maneuvers (or not) and evolution.
