Metabolic and transcriptional effects of bazedoxifene/conjugated estrogens in a model of obesity-associated breast cancer risk.
Article in JCI insight, 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
Many risk-eligible women refuse tamoxifen for primary prevention of breast cancer due to concerns about common side effects such as vasomotor symptoms. Tamoxifen may also induce or worsen insulin resistance and hypertriglyceridemia, especially in women with obesity. The combination of bazedoxifene and conjugated estrogens (BZA/CE) reduces vasomotor symptoms and is currently undergoing evaluation for breast cancer risk reduction. However, the impact of BZA/CE on insulin resistance and metabolic health, particularly in those with excess adiposity, is understudied. Here, we examined the effects of obesity on response to BZA/CE in a rat model of breast cancer risk using older ovary-intact rats. Female Wistar rats received carcinogen to increase mammary cancer risk and were fed a high-fat diet to promote obesity. Lean and obese rats were selected based on adiposity, and then randomized to BZA/CE or vehicle for 8 weeks. BZA/CE reduced adiposity, enriched small (insulin-sensitive) mammary adipocytes, increased the abundance of beneficial metabolic gut microbes (Faecalbaculum rodentium and Odoribacter laneus), and reversed obesity-associated changes in lipids and adipokines. BZA/CE also reversed obesity-induced mammary enrichment of cell proliferation pathways, consistent with risk-reducing effects. Together, these data support the use of BZA/CE to improve metabolic health and reduce breast cancer risk in individuals with obesity.
