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

objectiveEndoscopy is the gold-standard diagnostic modality for many pediatric airway disorders but does not enable quantitative assessment of airway morphology. In a series of pediatric patients, we aim to demonstrate that structure from motion (SfM) photogrammetry, a computer-vision algorithm, can accurately reconstruct three-dimensional (3D) models of laryngeal anatomy directly from bronchoscopy videos. STUDY

designProspective case series.

settingTertiary academic pediatric hospital.

methodsPediatric patients undergoing direct laryngoscopy/bronchoscopy and same-day neck and chest computed tomography (CT) as a part of clinical care were recruited. Optical calibration of the imaging system occurred after each bronchoscopy. SfM was used to reconstruct 3D surfaces from bronchoscopy videos. SfM-reconstructed surfaces were compared against CT-derived geometries to determine reconstruction accuracy at glottic and subglottic levels.

resultsSfM reconstruction was successfully completed for all four patients. Circular equivalent diameter (D

conclusionWe demonstrate the feasibility of reconstructing laryngeal anatomy with high fidelity from SfM photogrammetry in a clinical series of pediatric patients. This reproducible method provides highly accurate anatomic models directly from endoscopy, enabling quantitative assessment without CT scanning and radiation exposure. This approach has the potential to impact many areas of otolaryngology, including virtual surgical planning, simulation, and family counseling.
