Endoscopic surveillance of poor oral hygiene in vulnerable patients at pneumonia risk.
Observational study in Clinical oral investigations, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectivesThis study evaluated the routine use of upper gastrointestinal (UGI) endoscopy combined with oral-pharynx-larynx surveillance to assess oral hygiene and its impact on pneumonia development in vulnerable patients. MATERIALS AND
methodsThis retrospective observational study included 411 hospitalized participants who underwent UGI endoscopy with concurrent oral-pharynx-larynx examination. Poor oral hygiene was identified based on endoscopic findings, including nasopharyngeal pooling secretions, diffuse inspissated oral secretions, and food particles, tartar, or plaque. Among these, 68 participants were identified with poor oral hygiene, while the remaining 343 participants comprised the control group. Records of basic and clinical characteristics were analyzed.
resultsGastroenterologists identified 2.6% (68/2,567) of participants with poor oral hygiene during endoscopy. The frequency of pneumonia was notably higher in the poor oral hygiene group (3.0 ± 1.5 episodes/person-year) compared to the control group (0.6 ± 2.0 episodes/person-year, p < 0.001). Multivariable analysis showed that poor oral hygiene significantly increased the risk of pneumonia requiring hospitalization (p < 0.001). Enteral tube feeding was also independently associated with increased pneumonia risk (p = 0.003). Kaplan-Meier analysis indicated a significantly higher cumulative incidence of pneumonia in the poor oral hygiene group.
conclusionsPoor oral hygiene identified during the endoscopic examination was significantly associated with an increased risk of pneumonia requiring hospitalization. CLINICAL RELEVANCE: Gastroenterologists can identify vulnerable patients with poor oral hygiene during endoscopy, providing an opportunity for referral to dentists or primary caregivers for timely intervention and management.
