The impact of perioperative oral care on postoperative infection in patients with esophageal cancer: a retrospective cohort study before and during COVID-19.

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
purposeThis study evaluated the impact of preoperative oral hygiene on the incidence of postoperative pneumonia (PP) and surgical site infection (SSI) in patients undergoing esophageal cancer surgery considering the influence of COVID-19 and developing effective perioperative oral care methods.
methodsThe medical records of patients who underwent esophageal cancer surgery between January 2017 and March 2022 were analyzed. Patient characteristics and the incidence of PP and SSI before and during COVID-19 were compared. A multiple logistic regression analysis was performed with PP and SSI as the dependent variables.
resultsThis analysis included 207 participants. The mean age was 66.6 ± 8.3 years old, and 78.3% were male. There were no significant changes in the incidence of PP or SSI before and during the COVID-19 pandemic. Preoperative xerostomia significantly increased the risk of PP (odds ratio = 3.34, 95% confidence interval 1.10-10.08, p = 0.033), an advanced cancer stage, and recurrent laryngeal nerve palsy. Surgical procedures and reconstructive organs, but not preoperative oral hygiene factors, were associated with SSI.
conclusionsThe incidence of PP and SSI in patients with esophageal cancer showed no marked changes before or during the COVID-19 pandemic. Managing preoperative xerostomia may be crucial for reducing the risk of PP.
