Combination of computed tomography measurements and flexible video bronchoscope guidance for accurate placement of the right-sided double-lumen tube: a randomised controlled trial.
Trial report in BMJ open, 2023. 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
objectiveTo compare the modified strategy for the right-sided double-lumen tube (R-DLT) placement using a combination of CT measurements and flexible video bronchoscopy guidance with traditional bronchoscopy technique. TRIAL DESIGN, SETTING AND
participantsDouble-blind, parallel randomised control trial at a tertiary care medical centre in China. 100 patients undergoing video-assisted thoracoscopic surgery and requiring R-DLT were randomly allocated to the control group and the intervention group.
interventionThe control group used the traditional bronchoscopy-guided technique. In the intervention group, the length and anteroposterior diameter of the right main bronchus (RMB) were measured on CT images to select the side and size of the Rüsch tube, and then a black depth marker was placed on the tube according to the difference between the length of the RMB and the bronchial cuff. Under the guidance of bronchoscopy, the depth marker should be placed parallel to the tracheal carina and a characteristic white line on the tube should be parallel to the midline of the tracheal carina. MAIN OUTCOMES: The primary endpoint was the positioning of right upper lobe (RUL) ventilatory slot and RUL bronchial orifice. The secondary endpoints included intubation data and perioperative adverse events.
resultsCompared with the control group, our modified strategy significantly increased the optimal and acceptable position rate (76% vs 98%, respectively; p<0.039), decreased the replacement rate (80% vs 94%; p=0.042), shortened the intubation time (101.4±7.3 s vs 75.2±8.1 s; p=0.019) and reduced the incidence of transient hypoxaemia (25% vs 6%; p=0.022), subglottic resistance (20% vs 6%; p=0.037), tracheobronchial injury (35% vs 13%; p=0.037) and postoperative RUL collapse (15% vs 2%; p=0.059).
conclusionThis study demonstrates the superiority of our strategy and provides a new viable method for R-DLT placement. TRIAL REGISTRATION NUMBER: Chinese Clinical Trial Registry (ChiCTR1900021676).
