Trends in nontraumatic intestinal perforation-related mortality among adults in the United States from 1999 to 2020: A nationwide CDC WONDER analysis.
Article in Medicine, 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
To characterize mortality trends associated with nontraumatic intestinal perforation (NIP) in the United States, which continue to remain poorly defined. NIP is defined as the loss of continuity of the bowel wall in which external trauma as an etiology has been excluded. NIP is a serious gastrointestinal emergency with limited national mortality trend data, particularly across various demographic and regional subgroups. NIP-related mortality data were extracted from the Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research database from 1999 to 2020. We analyzed age-adjusted mortality rates (AAMR) per 100,000 individuals and annual percent change (APCs) with 95% confidence interval (CI) in patients ≥ 15 years based on gender, race and geographical region. Overall, there were 122,161 NIP-related deaths among patients aged ≥ 15 years, with an increase in AAMR from 1.90 in 1999 to 2.0 in 2009 (APC: 0.19; CI: -0.33 to 0.71), and a gradual increase to 2.40 in 2020 (APC: 1.26; CI: 0.80 to 1.71). AAMR was lower in females compared to males in 1999 (2.0 vs 1.90; CI: 1.90 to 2.0). However, in 2020, AAMR values increased in females (2.20 vs 2.0; CI: 2.40 to 2.60; P < .05). AAMRs were higher in patients reported as non-Hispanic compared to Hispanic/Latinos (2.10 vs 1.50; CI: 2.10 to 2.10; P < .05). Variation in AAMR values across census regions was not significant. NIP-related AAMR was higher in nonmetropolitan than metropolitan areas (2.90 vs 1.90; CI: 2.10 to 2.10; P < .05). NIP-related mortality has risen among patients' ≥15 years. Higher AAMRs in females, non-Hispanic individuals, and nonmetropolitan populations highlight the need for targeted preventive efforts.
