Effect of pemafibrate in reducing intestinal long-chain fatty acid absorption and hepatic fibrosis in metabolic dysfunction-associated steatohepatitis rats.
Article in BMC gastroenterology, 2025. 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
backgroundPemafibrate helps regulate fatty acid dynamics in the liver, potentially preventing metabolic dysfunction-associated steatohepatitis (MASH). However, its effect on intestinal long-chain fatty acid (LCFA) metabolism in MASH remains unclear. Thus, we aimed to examine the influence of pemafibrate on intestinal LCFA metabolism and hepatic fibrosis in a MASH rat model.
methodsSprague-Dawley rats were fed a high-fat and high-cholesterol diet to induce MASH and then divided into pemafibrate-treated (pemafibrate (+)) and untreated (pemafibrate (-)) groups. Triglyceride deposition in the small intestine and fibrosis, along with α-smooth muscle actin level in the liver, were evaluated. Furthermore, the mRNA expression levels of genes associated with lipid metabolism in the small intestine and markers of fibrosis and hepatic stellate cells activation in the liver were measured.
resultsThe pemafibrate-treated group had markedly lower triglyceride deposition and lipid absorption in the intestine, and significantly lower levels of molecules involved in intestinal lipid regulation than the pemafibrate-untreated group. Moreover, hepatic fibrosis significantly improved, and the mRNA levels of fibrosis-related molecules and hepatic stellate cell activation factors significantly decreased in the pemafibrate-treated compared with those in the pemafibrate-untreated group.
conclusionsPemafibrate reduced lipid droplet formation and LCFA absorption in the intestinal tract and alleviated hepatic fibrosis in MASH model rats.
