Trends and racial-geographic disparities in mortality among US older adults with peripheral artery disease, 1999 to 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
backgroundPeripheral arterial disease (PAD) is a progressive vascular disorder among older adults that is associated with significant disability and elevated cardiovascular mortality. However, national mortality trends and disparities among US adults aged ≥65 years with PAD listed on death certificates have not been fully characterized.
methodsThis study evaluated national mortality trends and demographic disparities among US adults aged ≥65 years with PAD or selected peripheral vascular/arterial conditions. Using the CDC WONDER Multiple Cause of Death database (1999-2020), we conducted a retrospective population-based analysis. ICD-10 codes for peripheral vascular and arterial diseases were used to identify deaths in which PAD or associated peripheral arterial/vascular conditions were listed as an underlying or contributing cause of death. Age-adjusted mortality rates (AAMR) per 100,000 population were calculated using the 2000 US standard population. We used joinpoint regression to estimate annual percent change (APC) and average annual percent change (AAPC), with
resultsA total of 1,738,432 PAD-related deaths occurred among adults aged ≥65 years. The overall AAMR declined from 245.14 in 1999 to 145.82 in 2020. Mortality was higher among males than females (282.70 vs 215.26 in 1999; 173.84 vs 117.10 in 2020). Non-Hispanic Black individuals had the highest mortality burden (319.28; 179.12), whereas non-Hispanic Asian or Pacific Islander individuals had the lowest (116.56; 77.52). Adults aged ≥85 years exhibited the highest mortality (836.30; 473.61). Nonmetropolitan areas demonstrated higher mortality than metropolitan areas (268.35 vs 239.55 in 1999; 160.15 vs 142.88 in 2020). Regionally, the Midwest had the highest AAMR (265.61; 148.99), while the Northeast had the lowest (203.99; 127.07). State-level variation ranged from 281.89 in Ohio to 114.82 in Hawaii. Most deaths occurred in medical facilities (39.1%).
conclusionsMortality among older adults with PAD or selected peripheral vascular/arterial conditions listed on death certificates declined overall. However, demographic and geographic disparities persisted, with recent increases observed after 2018. Targeted prevention, early detection, and modification of risk factors are needed for high-risk older populations.
