LEPR Contributes to Lung Squamous Cell Carcinoma: Insights From Mendelian Randomization and Experimental Studies.
Article in Cancer informatics, 2026. 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: The involvement of certain adipokines link to carcinogenesis, development, and prognosis. However, the roles of adipokines in lung cancer and its histological subtypes remains indistinct. Therefore, the aims of this study are to explore the causal relationship between adipokines and lung cancers. Methods: Summary-level data for exposures (six adipokines) and outcomes (lung cancer and its histological subtypes) were collected from the IEU OpenGWAS, International Lung Cancer Consortium (ILCCO) and lectures. Two-sample mendelian randomization (MR) was conducted to estimate the causality by employing single nucleotide polymorphisms (SNPs) as instrument variables (IVs). Human tissue microarray and immunohistochemistry (IHC) analysis validated the adipokines expression. Functional effects of LEPR in LUSC were assessed Results: Leptin receptor (LEPR) was associated with risk of lung squamous cell carcinoma (LUSC, OR: 1.05, 95% CI: 1.01-1.08; P < 0.0125), and no other adipokines associated with lung cancer and its histological subtypes (P > 0.05). Experimental results revealed that high expression of LEPR in LUSC tumor samples compared to adjacent normal samples, and associated with unfavorable survival status. Conclusion: These findings suggest that LEPR may play a critical role in the development and progression of LUSC, providing a potential target for therapeutic intervention.
