Trends in Dermatopolymyositis Mortality, 1999-2022: A Nationwide Population-Based Study, United States.
Article in Arthritis care & research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveWe evaluated trends in dermatopolymyositis (DPM) mortality relative to all-cause mortality in the United States from 1999 to 2022.
methodsWe used the Centers for Disease Control and Prevention's databases (Multiple Causes of Death for 1999-2020 and Provisional Mortality Statistics for 2021 and 2022) to obtain death counts for DPM and non-DPM (all causes other than DPM). We calculated age-standardized mortality rates (ASMRs) for both groups and computed the ratio of DPM-ASMR to non-DPM-ASMR for each of the 24 years. We performed joinpoint regression analysis to estimate annual percent change (APC) in DPM-ASMRs and non-DPM-ASMRs and in the DPM-ASMR to non-DPM-ASMR ratios overall and by sex, age, and race and ethnicity.
resultsThere were 12,882 DPM and 63,549,485 non-DPM deaths during 1999-2022. Mortality decreased at a higher APC (-3.8% [95% confidence interval (CI) -4.3% to -3.4%]) for DPM than for non-DPM (-1.2% [95% CI -1.5% to -0.9%]) until the start of the COVID-19 pandemic, when it increased for both at similar APCs. Consequently, the ratios of DPM-ASMRs to non-DPM-ASMRs decreased over these 24 years in all subgroups. The DPM-ASMR to non-DPM-ASMR ratios were higher in females than males and in younger individuals (≤64 years) than those aged ≥65 years. The odds of premature death were higher for DPM than for non-DPM. Individuals of non-Hispanic Black, Hispanic, and non-Hispanic other race and ethnicity had higher DPM-ASMR to non-DPM-ASMR ratios than White individuals.
conclusionDPM mortality decreased at a higher rate than all-cause mortality until the pandemic, when it proportionately increased for both DPM and all causes. Females, younger individuals, and individuals of Black, Hispanic, and non-Hispanic other race and ethnicity had higher DPM mortality relative to all-cause mortality. Findings highlight the need for improved screening, earlier intervention, and targeted efforts to address racial and ethnic disparities in DPM outcomes.
