Risk factors for early suspected ventilator-associated pneumonia in severe thoracic blunt trauma patient: A French national cohort study.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundVentilator-associated pneumonia (VAP) is the most common infection in severely injured patients requiring mechanical ventilation. Chest trauma has been identified as a significant risk factor for VAP. This study aimed to describe the risk factors for early VAP in patients with severe blunt thoracic trauma admitted to the intensive care unit (ICU) and receiving mechanical ventilation. MATERIALS AND
methodsA retrospective cohort study was conducted using data from a national registry including data from 17 French trauma centers during a period of seven years. The study included patients with severe blunt thoracic trauma requiring invasive mechanical ventilation. Data analysis focused on identifying independent risk factors for early suspected VAP (occurring within 48 hours to 5 days after ICU admission) using two models of logistic regression.
resultsFrom 31700 patients screened 712 patients were analyzed. Early suspected VAP occurred in 192 (27%) patients. The study identified several independent risk factors associated with early suspected VAP in patients with severe blunt thoracic trauma: male gender (OR= 2.77, 95%CI: 1.68-4.77, p < 0.001), ASA score >1 (OR= 1.64, 95%CI: 1.08-2.50, p = 0.019), injury severity score (ISS) >15 (OR=3.15, 95%CI: 1.13-11.99, p = 0.025), initial Glasgow Coma Scale (GCS) score <9 (OR=2.71, 95%CI: 1.88-3.96, p < 0.001), absolute thoracic abbreviated injury scale (AIS) (OR=1.51, 95%CI: 1.14-1.99, p = 0.003), and the number of packed red blood cells (PRBCs) transfused within the first 24 hours (OR=1.04, 95%CI: 1.00-1.08, p = 0.027). Prehospital antibiotic administration was identified as a protective factor (OR=0.54, 95%CI: 0.29-0.94, p = 0.028).
conclusionIn patients with severe blunt chest trauma receiving invasive mechanical ventilation, male gender, ASA score, ISS > 15, GCS < 9, thoracic AIS and number of PRBCs transfused were independent risk factors for early suspected VAP. Prehospital antibiotic therapy was a protective factor, suggesting potential strategies for VAP prevention.
