The impact of lipidome on five inflammatory skin diseases: a Mendelian randomization study.
Article in Archives of dermatological research, 2024. 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
objectiveTwo-sample Mendelian randomization (TSMR) was employed to examine the association between lipidome and five inflammatory skin diseases.
methodTo evaluate the association between various molecular subtypes of lipidome and the risk of five inflammatory skin diseases, we analyzed a comprehensive GWAS dataset comprising 179 lipidome. The Two-Sample Mendelian Randomization (TSMR) method was employed to investigate causal relationships. Heterogeneity and pleiotropy were assessed using Cochran's Q test, MR-Egger intercept test, and MR-PRESSO global test. Additionally, a sensitivity analysis was conducted to evaluate the influence of individual single nucleotide polymorphisms on Mendelian Randomization study.
resultsUsing 179 serum lipidome as exposures and five common inflammatory skin diseases as outcomes, we investigated their associations in this large-scale study. Our findings reveal significant impacts of glycerophospholipids, glycerolipids, and sphingomyelins on inflammatory skin diseases. Glycerophospholipids were protective against pemphigus but predominantly posed risks for other inflammatory skin diseases. Specifically, phosphatidylcholine (16:0_0:0) exhibited the most significant risk association with lichen planus (OR = 1.25, 95% CI 1.11-1.40, P < 0.001). Conversely, glycerolipids showed no effect on lichen planus but were protective against pemphigus while potentially posing risks for other conditions. Triacylglycerol (46:2) showed the most substantial risk association with vitiligo (OR = 1.99, 95% CI 1.35-2.93, P < 0.001). Furthermore, sphingomyelins had no effect on atopic dermatitis but posed potential risks for other inflammatory skin diseases. Sphingomyelin (d40:1) notably emerged as a significant risk factor for pemphigus (OR = 1.91, 95% CI 1.37-2.66, P < 0.001).
conclusionsThis study has elucidated the potential harmful effects of glycerophospholipids, glycerolipids, and sphingomyelins on inflammatory skin diseases, while also providing valuable insights for future research into the pathophysiology, prevention and treatment of these conditions.
