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.
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: Khat contains alkaloids, tannins, and flavonoids with physiological and pathological effects. In Yemen, anorectal diseases, including hemorrhoids, are prevalent, and hemorrhoidectomy is frequently performed. Purpose: This study evaluates the relationship between chronic khat chewing and high-grade hemorrhoidal disease, as well as post-operative complications such as bleeding and pain. Patients and Methods: This prospective cross-sectional study included 1,896 patients aged 16-85 years, meeting the inclusion criteria were included and followed for three months. Patients Were Divided Into Two Groups: Chronic khat chewers (n=1,492) and non-khat chewers (n=404) Data included khat habits, clinical assessments, digital rectal exams, anoproctoscopy, intraoperative findings, and post-operative outcomes. Results: Chronic khat chewing was strongly associated with thrombosed grade IV hemorrhoidal disease. Among khat chewers, 90% had hemorrhoids, with 75% requiring hemorrhoidectomy or hemorrhoidopexy, compared to 25% in non-chewers, where half underwent hemorrhoidopexy. The odds ratio (OR) for hemorrhoids in khat chewers was 27.04. Gender-specific analysis showed a six-fold higher OR for hemorrhoids in khat-chewing females versus non-chewing females. Post-operative complications, including bleeding and severe pain, were significantly higher in male khat chewers (p < 0.05), while no significant differences were observed in females. Conclusion: Chronic khat chewing is strongly associated with high-grade hemorrhoidal disease and increased post-operative complications. Mechanisms include chronic constipation, increased anal sphincter tone, and prolonged sitting. These findings highlight the need for public health strategies to reduce khat use and tailored clinical approaches to improve outcomes. Future research should focus on establishing causality, identifying confounders, dose-response relationships, and exploring gender-specific management strategies that target both mechanical and pharmacological factors to optimize surgical care and long-term outcomes.
