Exploring the causal relationship between obesity, immune cell characteristics and cervical cancer risk using Mendelian randomization.

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
backgroundCervical cancer is a common malignancy among women worldwide. Obesity has been linked to numerous cancers through mechanisms involving hormonal disruption and chronic inflammation, while immune function variations may influence individual cancer susceptibility. However, the causal relationships between obesity, immune characteristics, and cervical cancer development remain unclear.
methodsThis study employed Mendelian randomization (MR) using single nucleotide polymorphisms (SNPs) as genetic instrumental variables to analyze causal relationships between obesity, immune cell composition, HLA expression, and cervical cancer risk. Multiple MR analytical methods (MR Egger, inverse variance weighted, weighted median, and weighted mode) were used for validation, with forest plots, scatter plots, and funnel plots used to assess result robustness.
resultsFindings regarding obesity and cervical cancer were inconsistent: one analysis showed no significant causal relationship (OR ≈ 1.00, p > 0.05), while another supported a causal association. Specific immune cell populations were positively associated with cervical cancer risk, and HLA expression (particularly HLA-DRB and CD33+/HLA-DR + cells) was linked to increased cervical cancer risk. Notably, CD4+/CD8 + regulatory T cells were negatively associated with cervical cancer risk, suggesting a potential protective effect.
conclusionThis study provides genetic epidemiological evidence for potential causal relationships between obesity, immune cell composition, HLA expression, and cervical cancer risk. These findings reveal the importance of immune function in HPV-related carcinogenesis and offer new perspectives for cervical cancer prevention and targeted treatment.
