Impact of obesity on double-lumen endobronchial tube displacement after lateral decubitus positioning.
Article in Korean journal of anesthesiology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundDouble-lumen endobronchial tube (DLT) displacement, defined as migration of the DLT > 15 mm from optimal position, may threaten patient safety. Lateral decubitus positioning (LDP) of the patient can induce DLT displacement; however, little is known regarding the predictors for DLT displacement after this maneuver. Obesity may further aggravate DLT displacement by distorting mediastinal anatomy, but no comprehensive data exist concerning the impact of obesity on DLT displacement after LDP. Therefore, we evaluated the predictive value of preoperative risk factors, including obesity, for DLT displacement after LDP in patients who underwent pulmonary resection.
methodsData of patients who underwent pulmonary resection between July 2020 and July 2021 were retrospectively reviewed. Age, sex, height, weight, body mass index, left main bronchus diameter, DLT size, lateral decubitus direction, DLT depth, patient height divided by the DLT depths in supine and lateral decubitus positions (H/Dsupine and H/Dlateral, respectively), and extent of DLT dislocation were assessed. Logistic regression analysis identified risk factors, and the optimal cutoff values for continuous variables were determined using receiver operating characteristic curve analysis.
resultsData from 428 patients were analyzed. DLT displacement was observed in 52 patients (12.1%). Obesity and H/Dsupine were independent predictors for DLT displacement after LDP (odds ratio [OR]: 5.69, 95% CI [2.89, 11.23], P < 0.001 and OR: 8.28, 95% CI [2.92, 23.48], P < 0.001, respectively).
conclusionsObesity was significantly associated with DLT displacement after LDP. Pre-emptively advancing the DLT from its optimal position before LDP may be advantageous in patients with obesity.
