Study on risk factors of Montgomery T-tube extraction in patients with post-tracheotomy tracheal stenosis based on Cox regression analysis.
Observational study in BMC pulmonary medicine, 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
backgroundAlthough Montgomery T-tube implantation has become an effective method for treating tracheal stenosis, the T-tube needs to be removed as a temporary treatment. At present, there is still a lack of research on the relevant factors affecting T-tube extraction. Therefore, we aimed to explore the clinical characteristics of post-tracheotomy tracheal stenosis (PTTS) disease and the risk factors affecting Montgomery T-tube extraction.
methodsRetrospective analysis of patients who underwent Montgomery T-tube implantation in the Respiratory and Critical Care Medicine of Emergency General Hospital and the Department of Respiratory Medicine at Dongzhimen Hospital from June 2014 to September 2024. They were followed up for at least 6 months. T-tube extraction was used as the main outcome measure. A logarithmic rank test was used to analyze the association between clinical characteristics and T-tube extraction. Kaplan-Meier analysis was performed to analyze the rate of T-tube extraction. Multivariate stepwise Cox regression analysis was used to explore the variables that may affect the association of T-tube extraction.
resultsA total of 49 patients were included, and 18 (36.7%) patients had successful extraction. In the Kaplan-Meier analysis, the rate of extubation was lower in patients with BMI ≥ 24, diabetes mellitus, and a narrow distance of less than or equal to 1 cm from the glottis (P < 0.05). In multivariate Cox regression analysis, cerebrovascular disease (HR 0.341, 95% confidence interval [CI] 0.127-0.918) and diabetes mellitus (HR 0.216, 95% confidence interval [CI] 0.049-0.959) may be independent risk factors for T-tube extraction.
conclusionsDiabetes mellitus and cerebrovascular diseases are independent risk factors for T-tube extraction, and more attention should be paid to these patients in clinical practice. CLINICAL TRIAL NUMBER: This study is a retrospective observational study, and no clinical trial registration number was applied for.
