Investigating the relationship between breast cancer risk factors and an AI-generated mammographic texture feature in the Nurses' Health Study II.
Article in NPJ breast cancer, 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
The mammogram risk score (MRS), an AI-driven mammographic texture feature, strongly predicts breast cancer risk independently of breast density, though underlying mechanisms remain unclear. Using data from the Nurses' Health Study II (292 cases, 561 controls), we validated MRS's association with breast cancer and evaluated its relationships with established breast cancer risk factors through observational analyses, polygenic score analyses, and Mendelian randomization. MRS was significantly associated with breast cancer risk before (OR=1.92 per SD increase; 95% CI:1.57 to 2.35; 10-year AUC=0.69) and after adjustment for predicted BI-RADS density (OR=1.85; 95% CI:1.49 to 2.30). Early life body size and adult body mass index (BMI) were inversely associated with MRS, while benign breast disease history and predicted BI-RADS density showed positive associations; after adjusting for density, associations between MRS and the other three risk factors were attenuated. Polygenic score analyses and Mendelian randomization consistently demonstrated significant positive associations between genetic predictors of breast density measures (dense area, percent density, predicted BI-RADS density) and MRS. After adjusting for predicted BI-RADS density and BMI, genetic predictors of higher waist-to-hip ratio were significantly associated with increased MRS. Our findings reveal robust associations between breast density measures and MRS and suggest a potential impact of central obesity on MRS. Future larger-scale validation studies are needed.
