Is COVID-19 Infection A Risk Factor for Intubation-Related Acquired Airway Stenosis?
Article in Otolaryngology--head and neck surgery : official journal of American Academy of Otolaryngology-Head and Neck Surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
objectiveTo determine whether COVID-19 is a risk factor for developing airway stenosis in intubated patients. STUDY
designRetrospective case-control study with planned chart review.
settingTemple University Health Systems hospitals in Philadelphia, PA.
methodsChart review of patients 18 to 90 years old diagnosed with COVID-19 who underwent endotracheal intubation and had a post-extubation CT scan at our institution between February 2020 and December 2022 was performed. Patients without COVID-19 matched for age, sex, and BMI who were intubated within one year served as a control group. Outcome variables included endoscopic and radiographic evidence of airway stenosis. Descriptive statistics were analyzed using Chi-squared and unpaired two-tailed T-test analyses for cohort comparison.
resultsOne hundred five COVID-positive and 101 COVID-negative met inclusion criteria. The mean age was 58.6 years. Mean endotracheal tube size was 8.05 for COVID-positive and 7.72 for COVID-negative patients (P = .0075). Twenty-six (24.76%) COVID-positive and 45 (44.55%) COVID-negative patients had COPD (P = .0016). Length of intubation was 8.8 days in COVID-positive patients and 3.5 days for COVID-negative patients (P < .0001). Thirty-five (33.98%) COVID-positive and 1 (0.99%) COVID-negative patient were ventilated while prone (P = .0002). Seventy-eight (75%) COVID-positive and 38 (41.76%) COVID-negative patients received intravenous steroids (P = .0001). Mean length of stay was 38.81 days for COVID-positive and 17.16 days for COVID-negative patients (P < .0004). Six (5.77%) COVID-positive and 2 (1.3%) COVID-negative patients developed airway stenosis (P = .202).
conclusionPatients with COVID-19 infection were not at an increased risk for intubation-related airway stenosis. LEVEL OF EVIDENCE: IV.
