Risk Factors of Difficult Intubation in Patients with Severe Obesity Undergoing Bariatric Surgery: A Retrospective Cohort Study.
Article in Obesity surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundObesity poses significant challenges by altering upper airway anatomy and making mask ventilation and tracheal intubation difficult. In 2023, 46.1% women and 35.9% men > 18 years were classified as obese in Qatar, yet intubation complications in this group have not been extensively studied. The aim of this study was to evaluate the frequency and types of intubation complications in adults with severe obesity undergoing bariatric surgery and to identify incidence of difficult intubation and associated risk factors.
methodsIn this retrospective cohort study, 2421 patients (1664 females and 746 males) were analyzed. All patients with severe obesity aged over 18 years with a BMI of 40 kg/m
resultsNone of the patients experienced any complications of interest. Video laryngoscope was used in 85 patients (3.5%), first-attempt intubation success rate was 95.4%, with more than one attempt required in 4.6% of cases. Logistic regression revealed that the odds of complicated intubation were 1.5 times higher in patients with a BMI > 60, 8.9 times higher in those with Cormack-Lehane class IV, and 5.1 times higher in patients with Mallampati score of IV. Comorbidities increased the odds by 1.3 times, with asthmatic patients having 2.1-fold higher odds.
conclusionThis study highlights the challenges of tracheal intubation in patients with severe obesity undergoing bariatric surgery and the need for tailored strategies to manage these difficulties.
