Indirect assessment of hemorrhoid incidence using invasive treatment data in Japan: A 5-year study based on nationwide health insurance claims.
Article in Annals of gastroenterological surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Aim: The epidemiology of hemorrhoids is challenging because of variability in sampling methodologies and diagnostic criteria across different studies. This study indirectly clarified the epidemiology of hemorrhoids by investigating the number of invasive treatments for hemorrhoids (ITH) using a nationwide healthcare claims database. Methods: The annual number and rate of ITH procedures per 100 000 people during 2018-2022 were examined. ITH covered by the Japanese healthcare insurance includes sclerotherapy, rubber band ligation, infrared coagulation, thrombectomy, hemorrhoidectomy, and stapled hemorrhoidopexy. The demographic peak patterns in the sex- and age-stratified data were analyzed. Annual trends were evaluated using the Jonckheere-Terpstra trend test or Poisson regression model. Results: Over the 5-year period, the total number of ITH was 697 838, with a rate of 110.5 per 100 000 person-years. The male-to-female ratio was 1.2:1, indicating slight male predominance. Demographic peak analysis revealed bimodal peaks in males aged 40-44 and 75-79 years, and in females aged 35-39 and 75-79 years. No significant changes were observed in all ITH procedures. The age-adjusted number across all age groups per 100 000 person-years demonstrated annual decreasing trends for males but increasing trends for females ( Conclusion: Distinct bimodal ITH peaks were observed in males and females in their 30s-40s and 70s. These findings provide valuable insights into the epidemiology of hemorrhoids.
