Polygenic risk of coronary artery disease for long-term survivors of breast cancer.
Article in Journal of the National Cancer Institute, 2025. 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
backgroundCardiovascular disease is a leading cause of death for long-term breast cancer survivors. We evaluated whether a polygenic risk score for coronary artery disease (CAD-PRS) was associated with the risk of incident CAD for survivors of unilateral or contralateral breast cancer.
methodsThe study included 1307 women with breast cancer first diagnosed at younger than 55 years of age who participated in the Women's Environmental Cancer and Radiation Epidemiology Follow-up Study. The CAD-PRS was based on a PRS developed and validated in a separate population. We modeled the association between incident CAD and the CAD-PRS, adjusting for age, CAD risk factors, first (and second) breast cancer treatment, study recruitment phase, and genetic population stratification. We also explored whether the risk of CAD depended on interactions between the CAD-PRS and cardiotoxic cancer treatment.
resultsThere were 66 incident CAD diagnoses reported at a median of 16 years after breast cancer diagnosis. Participants with CAD-PRS at or above the median had a 2.48-times increased risk of CAD (95% confidence interval [CI] = 1.44 to 4.29) relative to participants with CAD-PRS below the median. Anthracycline-based chemotherapy was associated with increased CAD risk (hazard ratio [HR] = 2.04, 95% CI = 1.04 to 3.98), and the association was not modified by the CAD-PRS. The association between incident CAD and left-sided radiation therapy (RT) was increased for those with CAD-PRS at or above the median (HR = 2.90, 95% CI = 1.26 to 6.68) but not for those with CAD-PRS below the median (HR = 0.96, 95% CI = 0.32 to 2.88). There was evidence of super-additive interaction between the CAD-PRS and left-sided RT (relative excess risk due to interaction = 2.06, 95% CI = 0.05 to 4.06).
conclusionA genome-wide CAD-PRS was associated with nonfatal CAD risk for long-term breast cancer survivors, providing potential utility for personalized cardiovascular care, particularly after RT.
