National trends and disparities in non-cancer mortality among older adults with oral cancer in the United States, 1999-2020.
Article in Frontiers in oncology, 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
Background: As survival rates for oral cancer (OC) patients improve, non-cancer-related diseases, particularly cardiovascular disease (CVD) and respiratory disease (RD), pose significant threats to long-term health outcomes. Understanding shifts in non-cancer mortality is crucial for optimizing survivorship care. OC predominantly affects individuals of advanced age. This study aimed to analyze national trends in non-cancer mortality among older adults with OC and identify key factors contributing to these disparities. Methods: Mortality data from the CDC WONDER Multiple Cause of Death database were used to examine deaths among individuals aged ≥ 65 years from 1999 to 2020. Age-adjusted mortality rates (AAMRs) were computed, and temporal trends were assessed using Joinpoint regression. A decomposition analysis for 2015-2020 identified key factors driving recent increases in mortality rates. Results: A total of 7,460 non-cancer-related deaths were recorded, with 3,485 attributed to CVD (47%) and 1,472 to RD (20%). The overall AAMR was 0.837, with higher rates observed in males (1.197), White individuals (0.849), residents of the West (0.909), and those living in nonmetropolitan areas (0.874). Mortality declined from 1999 to 2014 but increased significantly thereafter (APC = 8.085), with the sharpest increases observed in females (APC = 11.358) and the Southern region (APC = 10.616). CVD mortality consistently exceeded RD mortality across all subgroups. Decomposition analysis indicated that population growth and rising age-specific mortality rates were the primary contributors to the observed increases in mortality. Conclusion: Non-cancer mortality, particularly from CVD and RD, is rising among older OC survivors, with notable demographic and geographic disparities. Integrating long-term cardiopulmonary management and enhancing chronic disease prevention efforts could reduce non-cancer mortality in this vulnerable population.
