Trends and disparities in amyloidosis and cardiovascular disease mortality: a population-based retrospective study in the United States (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
backgroundAmyloidosis is increasingly recognized as a contributor to heart failure, particularly among older adults and patients with heart failure with preserved ejection fraction (HFpEF). Despite advances in diagnostic imaging and disease-modifying therapies, amyloidosis remains underdiagnosed in many settings, and population-level data examining its co-occurrence with cardiovascular disease on death certificates are limited. This study examined two decades of national mortality data to evaluate deaths co-coded with amyloidosis and cardiovascular disease (CVD) in the United States and to assess temporal trends and demographic disparities in age-adjusted mortality rates.
methodsA retrospective analysis was conducted using mortality data from the CDC WONDER database spanning 1999-2020. Age-adjusted mortality rates (AAMRs) per 1,000,000 persons were calculated, and trends were assessed using Average Annual Percentage Change (AAPC) and Annual Percent Change (APC) using Joinpoint 5.0.2.
resultsBetween 1999 and 2020, 26,391 amyloidosis and CVD-related deaths occurred among adults aged 25 years and older in the United States. The overall AAMR for deaths co-coded with amyloidosis and CVD increased from 4.40 in 1999 to 9.31 in 2020, with an AAPC of 3.49 (p < 0.001). The most pronounced increase occurred between 2018 and 2020 (APC: 13.60). Rates were higher among men than women, with both sexes showing a marked increase in the last decade. African American or Black individuals had the highest rates (11.40), followed by White (5.11) and Hispanic (3.86) individuals. Rates were highest in the Northeast region (6.71). Metropolitan areas had higher rates than non-metropolitan areas (5.73 vs. 4.76), with a more pronounced increase in metropolitan regions.
conclusionsAge-adjusted mortality rates for deaths co-coded with amyloidosis and cardiovascular disease have increased over time, likely reflecting improved recognition and documentation. Higher rates of co-coded deaths were noted among men, African Americans, and individuals in the Northeast region, highlighting potential disparities in diagnostic access and recognition.
