Oral care reduces incidence of pneumonia after esophagectomy: systematic review and meta-analysis.
Synthesis in Langenbeck's archives of surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
purposePost-operative pneumonia after esophagectomy is a major contributor to morbidity and mortality. Prior studies have demonstrated a link between the presence of pathologic oral flora and the development of aspiration pneumonia. The objective of this systematic review and meta-analysis was to evaluate the effect of pre-operative oral care on the incidence of post-operative pneumonia after esophagectomy.
methodsA systematic search of the literature was performed on September 2, 2022. Screening of titles and abstracts, full-text articles, and evaluation of methodological quality was performed by two authors. Case reports, conference proceedings, and animal studies were excluded. A meta-analysis of peri-operative oral care on the odds of post-operative pneumonia after esophagectomy was performed using Revman 5.4.1 with a Mantel-Haenszel, random-effects model.
resultsA total of 736 records underwent title and abstract screening, leading to 28 full-text studies evaluated for eligibility. A total of nine studies met the inclusion criteria and underwent meta-analysis. Meta-analysis revealed a significant reduction in post-operative pneumonia among patients undergoing pre-operative oral care intervention compared to those without an oral care intervention (OR 0.57, 95% CI 0.43-0.74, p < 0.0001; I
conclusionPre-operative oral care interventions have significant potential in the reduction of post-operative pneumonia after esophagectomy. North American prospective studies, as well as studies on the cost-benefit analysis, are required.
