Article in Annals of gastroenterological surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 nationwide observational study investigated recent trends in pancreatic cancer (PC) incidence and surgical management in Japan. Methods: Annual data on PC incidence (2016-2021) and surgical procedures (2016-2023) were obtained from the Cancer Information Database and the National Database of Health Insurance Claims and Specific Health Checkups (NDB), respectively. Surgical procedures were categorized by type (distal pancreatectomy (DP, 2016-2023)/pancreatoduodenectomy (PD, 2020-2023)) and approach (open/laparoscopic). Crude and age-adjusted rates per 100 000 person-years were calculated. Temporal trends were evaluated using linear and Poisson regression to estimate annual risk ratios (RRs). Results: Over the study period, the annual average PC incidence was 43 015, and the average number of PC surgery was 13 899. Age-adjusted PC incidence rates rose significantly among males, females, and both sexes (RR = 1.007, 1.016 and 1.011, respectively; Conclusion: These nationwide findings highlight age- and sex-specific signals-notably an apparent rise among young women and increased DP use among older adults-that warrant further validation.
