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
Objective: To evaluate the efficacy and long-term outcomes of Montgomery T-tube placement in patients with benign subglottic stenosis. Methods: We retrospectively analyzed the clinical data of 45 patients with benign subglottic stenosis treated with Montgomery T-tube placement at Beijing Tian Tan Hospital and Beijing Chuiyangliu Hospital between May 2015 and May 2025. The etiologies of tracheal stenosis were as follows: Iatrogenic in 41 patients (91.11%), including 29 patients (64.44%) with post-tracheotomy tracheal stenosis (PTTS) and 12 patients (26.67%) with post-intubation tracheal stenosis (PITS); post-traumatic in 1 patient (2.22%); post-tuberculosis in 2 patients (4.45%); and associated with chronic obstructive pulmonary disease (COPD) in 1 patient (2.22%). Results: All 45 patients successfully underwent T-tube placement. Among them, 39 patients achieved sustained airway patency and restored phonatory function following T-tube insertion, defined as successful retention (39/45, 86.67%). Six patients required tube removal within 2 weeks due to granulation tissue proliferation or mucus plug obstruction, defined as retention failure (6/45, 13.33%). Intraoperative complications primarily included mucosal lacerations (12 cases, 26.67%), all of which healed spontaneously within 1 week postoperatively. Short-term postoperative complications mainly comprised subglottic edema (31 cases, 68.89%), mucus plug obstruction (24 cases, 53.33%), and granulation tissue proliferation (10 cases, 22.22%). At the end of follow-up, 14 of the 39 patients (35.9%) were successfully decannulated and achieved long-term airway stability. The cumulative median tube retention time was 20.5 months. Of the 39 patients, 25 (64.10%) continued to require long-term T-tube retention. Multivariate regression analysis further indicated that a higher Cotton-Myer grade was independently associated with a significantly lower likelihood of successful decannulation ( Conclusion: Montgomery T-tube placement is a safe and effective interventional treatment for benign subglottic tracheal stenosis. It provides durable airway patency and functional improvement, particularly when surgical reconstruction is not feasible.
