Lipidomics of Bothrops atrox and Crotalus durissus ruruima venoms, the two major viperids involved in human envenomings in the Brazilian Amazon.
Article in Archives of toxicology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Recent investigations into the lipid constituents of snake venoms have yielded intriguing findings. Bothrops atrox and Crotalus durissus ruruima are the primary species responsible for snakebite envenomation in the Brazilian Amazon. However, the lipid compounds present in their venoms remain unknown. To address this gap, a lipidomic approach based on LC-HRMS (Liquid Chromatography-High-Resolution Mass Spectrometry) was employed to profile the lipid classes, subclasses, and species in the venoms of B. atrox and C. d. ruruima (yellow and white variations). The venom of B. atrox and the yellow variant of C. d. ruruima showed comparable profiles, with higher proportions of glycerolipids (55% and 46%, respectively) and glycerophospholipids (31% and 37%, respectively). In contrast, the white venom of C. d. ruruima showed a higher sphingolipid content (51%). Lipidomic analysis revealed multi-lipid species, with a high abundance of lipids from the subclasses sphingomyelin, phosphatidylcholine, monoalkylglycerol, and triacylglycerol, as well as monoacylglycerol, cardiolipins, glycerophosphoinositol, N-acylphosphatidylethanolamine, and cholesteryl esters. The lipids annotated are known to play diverse biological roles, particularly in cellular structure and signaling. This study is the first to characterize the lipid components in the venom of these snake species, contributing to a deeper understanding of their chemical composition and opening new avenues for investigating the roles of these compounds in snake venom.
