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

Background: Improvement in internal hemorrhoids is frequently observed after endoscopic submucosal dissection (ESD) for rectal intraepithelial neoplasia. This study investigated the effectiveness of rectal ESD in the management of internal hemorrhoids. Objectives: Twenty-three patients who underwent ESD for tumors adjacent to the dentate line and associated with internal hemorrhoids. Design: A single-arm, retrospective multi-center study. Methods: The focal improvement (at the scarring area after ESD) and complete improvement rates of hemorrhoids at follow-up colonoscopies were evaluated. Results: Most patients (87%) had mild hemorrhoids. The focal and complete improvement rates of hemorrhoids were 83% and 48%, respectively. Complete improvement rates were 75% (3/4), 42% (5/12), and 43% (3/7) for tumors involving ⩾1/2, between 1/4 and 1/2, and <1/4 of the circumference at the dentate line, respectively. No recurrence was observed after initial improvement, with a median observation period of 35 months. Conclusion: ESD may be an effective treatment for internal hemorrhoids.
