Linking Processed and Red Meat Consumption to Specific Lung Cancer Subtypes: A Mendelian Randomization Analysis.
Article in Current pharmaceutical biotechnology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveThe aim of this study was to elucidate the causal relationship between the consumption of processed and red meats (specifically pork, beef, and mutton) and susceptibility to various lung cancer types.
backgroundPrevious observational studies have indicated a potential cancer risk associated with red and processed meat consumption. However, a clear causal relationship remains undetermined. PURPOSE: Refining the study of the association between processed and red meat and lung cancer using a Mendelian randomization study.
methodWe harnessed the robustness of Two-Sample Mendelian Randomization, integrating data from the esteemed UK Biobank, capturing dietary habits with oncological datasets from the Transdisciplinary Research In Cancer of the Lung. The analytical approach was anchored in the inverse variance weighted (IVW) method, enriched by sensitivity analyses for result validation.
resultGenetic predispositions favoring processed meat consumption are linked to heightened risks of lung cancer [IVW analysis, OR=1.8203, 95%CI [1.1115,2.9811], p=0.0173], and in LUSC [IVW analysis, OR=2.9274, 95%CI [1.4810,5.7863], p=0.0020]. Beef was more important in lung cancer [IVW analysis, OR=4.6739, 95% CI [2.4947, 8.7570], p=0.000001], in LUSC [IVW analysis, OR=3.3251, 95%CI [1.2055,9.1717], p=0.0203] and in LUAD [IVW analysis, OR=7.1480, 95%CI [3.0074,16.9893], p=0.000008]. However, no significant links were identified between mutton or pork intake and lung cancer.
conclusionProcessed meat and beef consumption may elevate lung cancer risk. Additional research is warranted to investigate potential links between mutton or pork consumption and the risk of lung cancer.
