Causal effects of blood cells on breast cancer: Evidence from bidirectional Mendelian randomization combined with meta-analysis.
Synthesis in Medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
Recent studies suggest blood cells influence breast cancer, but no Mendelian randomization (MR) studies have confirmed a causal relationship between specific blood cell phenotypes and breast cancer. MR analysis of blood cell phenotypes used breast cancer data from Finngen R11, UKB, and open genome-wide association study databases. Meta-analyzed inverse variance weighted results were adjusted for multiple comparisons. The reverse relationship was also explored. MR and meta-analysis identified significant associations between specific blood cell phenotypes and breast cancer: neutrophil perturbation response (side fluorescence standard deviation of neutrophil 4 in response to alhydrogel perturbation): odds ratio (OR) = 0.967, P = .0009; neutrophil perturbation response (forward scatter median of neutrophil 4 in response to Pam3CSK4 perturbation): OR = 0.972, P = .031; white blood cell perturbation response (side scatter coefficient of variation of WBC 2 in response to nigericin perturbation): OR = 0.972, P = .031; white blood cell perturbation response (forward scatter coefficient of variation of WBC in response to Pam3CSK4 perturbation): OR = 1.042, P = 8.15 × 10-5. And there was no reverse result. Neutrophil perturbation response (side fluorescence standard deviation of neutrophil 4 in response to alhydrogel perturbation) and white blood cell perturbation response (side scatter coefficient of variation of WBC 2 in response to nigericin perturbation) are protective factors for breast cancer. Conversely, neutrophil perturbation response (forward scatter median of neutrophil 4 in response to Pam3CSK4 perturbation) and white blood cell perturbation response (forward scatter coefficient of variation of WBC in response to Pam3CSK4 perturbation) are risk factors for breast cancer.
