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

Purpose: To evaluate the technical feasibility and ergonomic advantages of 4K three-dimensional exoscope systems (4K3D-ES) versus operative microscope (OM) in stapedotomy. Methods: A retrospective cohort analysis compared 140 consecutive stapedotomy procedures performed by two senior surgeons (4K3D-ES: Results: The 4K3D-ES system demonstrated technical feasibility across all stapedotomy procedures, achieving complete procedural success without intraoperative conversion to OM. Analysis of surgical efficiency metrics revealed statistically comparable performance between the two groups: total operative duration showed no significant difference ( Conclusion: 4K3D-ES demonstrates technical equivalence to OM while offering superior ergonomics and team-shared 3D visualization, establishing its viability for precision stapes surgery.
