Regional, demographic and temporal trends in anemia and malignant cancer-related mortality in U.S. older adults: a nationwide CDC WONDER analysis (1999-2020).

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
Purpose: Anemia and malignancy concurrently contribute to reduced quality of life, treatment intolerance, and increased morbidity and mortality, disproportionately affecting older adults, socioeconomically disadvantaged groups, and minority populations. Despite its clinical importance, national patterns and population-level disparities in the mortality burden associated with this comorbidity remain poorly characterized. This study aims to examine mortality trends associated with concurrent anemia and malignancy in the United States using CDC WONDER (Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research) database, with a focus on demographic and geographic disparities to inform targeted interventions. Methods: Mortality data from CDC WONDER were analyzed for individuals aged 65 years and older using ICD-10 codes C00-C97 for malignancies and D50-D64 for anemia. Age-adjusted mortality rates (AAMRs) and annual percent changes (APCs) were calculated by year, age, sex, race/ethnicity, cancer type, and geographic region. Subgroup analyses focused on common anemia-associated cancers, including colorectal, gastric, lung, ovarian, female genital, breast, prostate, and hematologic malignancies, based on national prevalence. Results: Between 1999 and 2020, there were 264,331 anemia and malignancy -related deaths among U.S. adults aged ≥65. The overall AAMR remained relatively stable moving from 31.5 in 1999 to 31.1 in 2020. A significant decline occurred through 2017 (APC: -0.86), followed by a sharp increase from 2017 to 2020 (APC: 4.63). Males had higher AAMRs than females (28.8 vs. 22.6). Black individuals had the highest mortality (42.4). The Midwest had the highest regional AAMR (30.6), while the South had the lowest (27.6). States in the top 90th percentile for AAMR included North Dakota, Maryland, Rhode Island, West Virginia, and DC. Nonmetropolitan areas had higher AAMRs than metropolitan ones (32.9 vs. 27.8). Colorectal cancer showed the largest decline (AAPC: -2.03) followed by gastric (AAPC: -1.96) and prostate cancer (AAPC: -1.40), while breast, lung, gynecological, and hematological cancers remained stable. Conclusion: Among adults aged ≥65, anemia and malignancy-related mortality declined until 2017 but increased sharply through 2020, with highest rates in males, Black individuals, and nonmetropolitan/Midwestern residents. Declines were seen in colorectal, gastric, and prostate cancers, while other cancers remained stable, highlighting the need for targeted interventions to reduce disparities.
