ALDH2 Deficiency Drives Proliferative Mammary Morphogenesis and Epithelial Cell Stemness via Oxidative Stress and Estrogen Receptor Activation.

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
Alcohol consumption has been linked to breast cancer, partly due to the accumulation of toxic aldehydes like acetaldehyde, a carcinogenic byproduct of ethanol metabolism. ALDH2, a key mitochondrial enzyme, detoxifies acetaldehyde and other harmful aldehydes that drive oxidative stress, DNA damage, and hormonal dysregulation, key factors in carcinogenesis. Despite the possible link between alcohol consumption and breast cancer risk, little is known about how ALDH2 deficiency itself, independent of alcohol exposure, affects mammary gland biology and cancer susceptibility. Genetic variants leading to ALDH2 deficiency are highly prevalent in East Asian populations, where individuals carrying inactive ALDH2 alleles experience impaired aldehyde detoxification. While these individuals are at increased risk for alcohol-related cancers, the impact of ALDH2 deficiency on mammary gland development and homeostasis in the absence of alcohol exposure remains unexplored. To address this, we utilized a C57BL/6-based ALDH2 knockout (
