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: Conventional multiport laparoscopic cholecystectomy (CMLC) is the gold standard for benign gallbladder disease. Single-incision laparoscopic cholecystectomy (SILC) offers superior cosmesis but has limited adoption due to technical challenges. We introduce the Ewha Method, a modified SILC technique using an articulating instrument to improve visualization, ergonomics, and safety. Methods: We retrospectively analyzed 530 patients who underwent SILC between November 2023 and August 2024. Surgical outcomes were compared between senior (n = 338) and junior (n = 192) surgeons. Difficult surgery (DS) was defined as conversion to CMLC or operative time >60 minutes. Multivariable analysis identified risk factors for DS, and the learning curve was evaluated. Results: The junior surgeon group included more high-risk patients, with higher proportions of elderly (≥65 years, 42.2% Conclusion: The Ewha Method standardizes SILC, ensuring safety and efficiency with a short learning curve and minimal complications. It may serve as a viable alternative to CMLC, warranting further validation in diverse clinical settings.
