Causal relationship between immune cells and bladder cancer: A bidirectional Mendelian randomization study.
Article in Medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND AND
objectivesPrior research has examined immune cell involvement in bladder cancer (BCa). This Mendelian randomization (MR) study investigated causal links between 731 immune cell traits and BCa risk, identifying potential immunotherapy targets. Immune cell data came from a Sardinian cohort (3757 individuals), and BCa data from genome-wide association studies. We used inverse variance weighting as the main analysis, with MR-Egger and weighted median methods for validation. Stability checks included sensitivity analyses. Sixteen immune traits (related to 4 immune signals: MFI, RC, AC, MP) showed significant BCa associations. Five increased risk (OR > 1, P < .05), while 11 were protective (OR < 1, P < .05). No reverse causality, heterogeneity, or horizontal pleiotropy was found (P > .05). This MR analysis demonstrates complex causal relationships between immune cell traits and BCa, offering new insights for immunotherapy and prevention.
