Dietary intake of antioxidant vitamins and risk of pancreatic cancer: the Japan public health center-based prospective study.
Article in European journal of nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeOxidative stress has been implicated in the development of pancreatic cancer, but the association between antioxidant vitamin intake and risk of pancreatic cancer in Asian populations has not been establish.
methodsWe investigated the association between antioxidant vitamin intake and pancreatic cancer risk in a Japanese population based on the Japan Public Health Center-based Prospective Study, a cohort study including 89,693 Japanese men and women aged 45–74 years. Baseline data on medical history, lifestyle factors, and antioxidant vitamin intake were collected via validated questionnaires. Multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated for quartiles of antioxidant vitamin intake.
resultsDuring an average follow-up was 15.1 years, we documented 581 incident pancreatic cancers. Our results did not indicate a potential inverse association between antioxidant vitamin intake and risk of pancreatic cancer. When stratified by body mass index, the inverse association between dietary retinol, β-carotene, α-carotene, and β-cryptoxanthin intake and risk of pancreatic cancer indicated a statistically significant association among those with BMI ≥ 25 but not BMI < 25. Corresponding multivariable hazard ratios for the highest versus lowest quartiles among BMI ≥ 25 were intake of retinol activity equivalents of 0.52 (0.31–0.86; P = 0.01), β-carotene equivalent of 0.53 (0.31–0.91; P = 0.01), α-carotene of 0.57 (0.33–0.97; P = 0.05), and β-cryptoxanthin of 0.56 (0.33–0.95; P = 0.02).
conclusionOur findings suggests that intake of antioxidant vitamins, particularly retinol activity equivalents and β-carotene equivalents, may play a role in the prevention of pancreatic cancer in overweight subjects.
