Inter-prefectural regional disparities in gastric cancer surgery: A Japanese nationwide population-based cohort study from 2014 to 2019.
Article in Annals of gastroenterological surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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: This study aimed to investigate the regional disparities in gastric cancer surgery in Japan. Methods: The annual incidence of gastric cancer and number of gastrectomies, board-certified surgeons in gastroenterology by the Japanese Society of Gastroenterological Surgery, and board-certified surgeons by the Japan Society for Endoscopic Surgery were evaluated by prefecture in Japan during 2014-2019. Medium-sized regional disparities were assessed using the Gini coefficient. Gastrectomies were further broken down by site (distal; proximal; total) and approach (open vs laparoscopic). Moreover, we compared the urban and rural regional disparities in all study variables. Results: The annual national average incidence of gastric cancer was 127 466 and the number of gastrectomies was 49 128. Gini coefficients for almost all variables, except for board-certified surgeons by the Japan Society of Endoscopic Surgery, were <0.2, indicating low inequality. The incidence of gastric cancer, the number of gastrectomies, and the aging rate were significantly higher in rural prefectures than in urban prefectures. Conclusion: Inter-prefectural regional disparities in gastric cancer surgery were generally small; however, both the incidence of gastric cancer and number of gastrectomies were higher in rural prefectures, where the aging rate was also increased. This study provides an overview of the landscape of gastric cancer care in Japan.
