1 · What the graph read from it

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.

2 · The registry

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 a common complication in intensive care unit (ICU) patients, which increases morbidity rates and adversely affects outcomes. The associated risk factors and outcomes remain controversial. The aim of the present study is to explore the risk factors and clinical outcomes of patients with VAP.

methodsTwo investigators conducted independent systematic Literature searches of Pubmed, Cochrane Database, Scopus, Medline, Science Direct and Epistemonikos databases published from inception to November 2024. The Newcastle-Ottawa Scale (NOS) was used to assess study quality. A meta-analysis was performed using the random-effects Model. The systematic review protocol was registered in the CRDdatabase 42024538138 of the Prospective International Registry of Systematic Reviews (PROSPERO). A subgroup analysis, bivariate meta-regression, and sensitivity analysis were performed. Publication bias was assessed using a funnel plot and Egger's test. Certainty of evidence was assessed using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) methodology.

resultsTwenty-two studies were included in the meta-analysis, with a total of 16,731 patients. Male gender odds ratio (OR) 1.30 (95% Confidence interval (CI) 1.18-1.44) p<0.05; the use of H2 blockers OR 2.24 (95% CI 1.50-3.37) p<0.05; tracheostomy OR 3.44 (95% CI 2.0-5.92) p<0.05; prior antibiotic treatment OR 1.52 (95% CI 1.08-2.15) p<0.05; reintubation OR 5.11 (95% CI 2.29-11.42) p<0.05; enteral feeding OR 4.73 (95% CI 2.54-8.78) p<0.05; Chronic Obstructive Pulmonary Disease (COPD) OR 1.52 (95% CI 1.10-2.09) p<0.05; impaired consciousness at hospital admission OR 3.14 (95% CI 1.28-7.69) p<0.05; nasogastric tube OR 2.94 (95% CI 1.56-5.53) p<0.05; use of neuromuscular blockers OR 1.30 (95% CI 1.13-1.49) p<0.05; trauma OR 1.47 (95% CI 1.12-1.93) p<0.05, and days of intubation prior to VAP OR 6.2 (95% CI 1.09-11.3). A p<0.05 significantly increased the risk of VAP. In patients with VAP, the average ICU stay was 12.7 days longer (95% CI: 9.6-15.8) p<0.05; the duration of mechanical ventilation was 12.3 days longer (95% CI: 9.27-15.34) p <0.05; the hospital stay was 16.1 days longer (95% CI: 10.8-21.5) p <0.05. The certainty of the evidence was low for most outcomes.

conclusionsMale gender, use of H2 blockers, tracheostomy, prior antibiotic treatment, reintubation, enteral feeding, COPD, impaired consciousness at hospital admission, nasogastric tube, use of neuromuscular blockers, trauma and days of intubation prior to VAP significantly increased the risk of VAP. In patients with VAP, ICU stay, duration of mechanical ventilation, and hospital stay presented significant increases.
