1 · What the graph read from it

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.

2 · The registry

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

introductionAs the established gold standard for difficult airway management, flexible bronchoscope-guided endotracheal intubation nonetheless carries certain technical constraints. This study is designed to conduct a comparative analysis of multiple indicators including nasotracheal intubation duration between the modified flexible lightwand (MFL) and the conventional flexible bronchoscope (FB). METHODS AND ANALYSIS: This prospective, single-centre, single-blind, parallel-group, randomised controlled trial will be conducted at a tertiary grade A university-affiliated hospital in China. The study plans to enrol 70 oromaxillofacial surgery patients requiring nasotracheal intubation under general anaesthesia. Participants will be randomly allocated to either the MFL group (n=35) or the FB group (n=35). ETHICS AND DISSEMINATION: This study has been approved by the Ethics Committee of the First Affiliated Hospital of Xiamen University (2025(210)). Written informed consent will be obtained from all participants. The research findings will be disseminated through publication in peer-reviewed journals and presentations at relevant academic conferences or forums. TRIAL REGISTRATION NUMBER: ChiCTR2500112183.
