Prevalence and risk factors for postextubation dysphagia in ICU patients with orotracheal intubation: a systematic review and meta-analysis.
Synthesis in Frontiers in medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
Background: Evidence suggests that 41% of ICU patients acquired postextubation dysphagia, substantially increasing the risk of aspiration and malnutrition. Studies on its prevalence and risk factors showed considerable variation. Our study aims to summarize the overall prevalence and identify risk factors for postextubation dysphagia in ICU patients undergoing orotracheal intubation. Methods: We searched PubMed, Embase, Web of Science, Cochrane Library, CINAHL, Medline, China National Knowledge Infrastructure, Wanfang, SinoMed, and Technology Journal Database for studies on postextubation dysphagia from inception to July 5, 2025. Two researchers independently conducted the literature screening, quality assessment, and extracted data. Meta-analysis was performed using Stata software 18.0 and Review Manager software 5.3. Results: Twenty-five studies were included, encompassing a total of 7,219 patients. The meta-analysis revealed that the overall prevalence of postextubation dysphagia was 35% (95% CI: 25-46). Age (OR = 1.03), age ≥ 65 years (OR = 2.72), age ≥ 70 years (OR = 2.34), Acute Physiology and Chronic Health Evaluation II (APACHE II) score (OR = 1.29), APACHE II score ≥ 15 points (OR = 4.69), arrhythmia (OR = 3.30), neurological disorders (OR = 3.77), tracheal intubation duration in hours (OR = 1.03), tracheal intubation duration in days (OR = 1.13), tracheal intubation duration ≥72 h (OR = 8.15), tracheal intubation duration ≥7 days (OR = 2.06), gastric tube retention (OR = 6.59), and gastric tube retention duration ≥72 h (OR = 3.43), emergency admission (OR = 2.30) were risk factors for postextubation dysphagia. Conclusion: The incidence of PED in ICU patients is relatively high, which is influenced by various factors. Based on the identified risk factors, clinical staff can early identify high-risk individuals and implement targeted preventive measures to avoid postextubation dysphagia.
