Pre-shaping double-lumen endotracheal tubes based on video laryngoscope blade curvature enhances first-attempt intubation success rate in patients undergoing thoracoscopic surgery: a randomized controlled trial.
Article in Frontiers in medicine, 2025. 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
Background: The widespread adoption of video laryngoscopes (VLs) in double-lumen endotracheal tube (DLT) intubation has not resolved controversies regarding their efficacy in improving first-attempt success rates. This study aimed to evaluate the safety and efficacy of pre-shaping DLTs according to the VL blade curvature for tracheal intubation in patients undergoing thoracoscopic surgery. Methods: A total of 90 patients scheduled for elective thoracoscopic surgery under general anesthesia with left-sided DLT intubation were enrolled. The patients were aged ≥18 years and had an American Society of Anesthesiologists (ASA) physical status I or II. All patients were divided into two groups using a random number table method: a video laryngoscope blade curvature-based pre-shaping group (Group P, Results: Compared to Group T, Group P demonstrated a significantly higher first-attempt intubation success rate (91.1% vs. 72.7%, Conclusion: Pre-shaping DLTs based on VL blade curvature improves the first-attempt intubation success rate while minimizing intubation-related trauma in thoracoscopic surgery.
