Socioeconomic inequalities and dynamic changes in sex differences in lifetime risks of peptic ulcer disease.
Article in Biology of sex differences, 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
backgroundPeptic ulcer disease (PUD) is a common digestive system disorder and an important risk factor for gastric cancer. While previous studies have extensively focused on using traditional indicators, lifetime risks of PUD remain relatively scarce.
methodsUsing Global Burden of Disease (GBD) 2021 data, we estimated lifetime risks of developing and dying from PUD by lifetable method.Trends were assessed by calculating the average annual percent change (AAPC) from 1990 to 2021. By computing the sex ratios(male to female) of lifetime risks and plotting time-trend graphs, we analyzed the dynamic evolution of sex differences.
resultsIn 2021, the global lifetime risk of developing from PUD was 3.21% (95% CI, 3.20%-3.22%), declining from 1990 (AAPC: -1.24; 95% CI, -1.37 to -1.11), with a more pronounced decrease among males (AAPC: -1.43; 95% CI, -1.53 to -1.33) than females (AAPC: -1.00; 95% CI, -1.10 to -0.89). The lifetime risk of dying from PUD was 0.35% (95% CI, 0.34%-0.35%), with a faster decline (AAPC, -2.25; 95% CI, -2.57 to -1.93), again with greater in males (AAPC: -2.73; 95% CI, -2.86 to -2.60) than in females (AAPC: -1.80; 95% CI, -2.00 to -1.60). Marked socioeconomic disparities were observed: high-SDI regions had the highest lifetime risk of developing but the lowest risk of dying, whereas low-SDI regions showed the opposite pattern. Across different SDI regions, the sex ratios of lifetime risk of PUD exhibited unique inflection points over three decades.
conclusionDespite substantial global declines in lifetime risks of PUD over the past three decades, our findings reveal persistent inequities by SDI, geography, and sex. These disparities underscore that access to timely diagnosis, eradication therapy, and advanced endoscopic care remains uneven, particularly in low-SDI regions and among females.
