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
introductionHeart failure (HF) remains a leading cause of death in the United States. While depression is known to affect 17-37% of HF patients, its contribution to recorded mortality is poorly characterized in national datasets. Death certificate documentation of comorbid depression in HF deaths provides insight into clinical recognition and reporting patterns rather than the comprehensive burden of disease.
aimsTo analyze temporal trends and demographic disparities in death certificate documentation of depression among decedents with HF as the underlying cause, using the CDC Multiple Causes of Death (MCD) database from 1999-2020. METHODOLOGY: A retrospective observational study was conducted using the CDC MCD database for adults aged ≥25 years in the U.S. from 1999-2020. Deaths with HF (ICD-10: I50) as the underlying cause and depression (ICD-10: F32) as a contributing cause were identified. Age-adjusted mortality rates (AAMRs) per 1,000,000 population were calculated using the 2000 U.S. standard population, and trends were assessed with Joinpoint regression, expressed as annual percentage change (APC) with 95% confidence intervals (CIs).
resultsA total of 3,593 deaths were recorded where HF was listed as the underlying cause and depression as a contributing cause. The overall AAMR for HF with depression showed a declining trend from 1999-2009 (APC = -6.24; 95% CI = -8.31 to -4.12), followed by a plateau from 2009-2020 (APC = 0.05; 95% CI = -0.31 to 0.42). Females accounted for 69.6% of deaths, with higher AAMRs than males. The highest mortality documentation occurred in metropolitan areas and among White individuals (95.1%).
conclusionsThis study reveals declining documentation of depression on HF-related death certificates through 2009, followed by stabilization thereafter. The low absolute count of 3,593 deaths across two decades indicates substantial under-ascertainment compared to the known clinical prevalence of depression in HF patients. These findings primarily reflect documentation and reporting patterns rather than the total mortality burden, emphasizing the need for improved recognition and recording of mental health comorbidities in cardiovascular disease surveillance.
