Decreases in circulating ANGPTL3/8 concentrations following retatrutide treatment parallel reductions in serum lipids.
Trial report in Diabetes, obesity & metabolism, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
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
aimsThe aim of this study was to determine if retatrutide, a triple agonist of glucose-dependent insulinotropic polypeptide (GIP) receptor, glucagon-like peptide 1 (GLP-1) receptor and glucagon (GCG) receptor, may lower serum triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C) levels in part by decreasing circulating concentrations of the angiopoietin-like protein 3/8 complex (ANGPTL3/8). MATERIALS AND
methodsIn post-hoc analyses of two phase 2 retatrutide trials, concentrations of ANGPTL3/8, ANGPTL4/8 complex (ANGPTL4/8), ANGPTL3 and ANGPTL4 were measured using dedicated immunoassays to determine percent changes from baseline. Correlations of ANGPTL protein and complex levels with lipid and metabolic parameters at baseline were analysed. Correlations of the changes in ANGPTL protein and complex levels versus the changes in lipid and metabolic parameters at study endpoints were also analysed. Direct effects of retatrutide itself, GIP, GLP-1, GCG and a GCG receptor (GCGR) antagonist antibody on ANGPTL3/8 secretion were studied in vitro using primary human hepatocytes.
resultsANGPTL3/8 reductions were observed with 8 and 12 mg retatrutide doses in participants with type 2 diabetes, and with 1, 4, 8 and 12 mg retatrutide doses in participants with obesity or overweight but without diabetes. In both cases, ANGPTL3/8 decreases paralleled retatrutide-induced reductions in TG and LDL-C. In primary human hepatocytes, both glucagon and retatrutide decreased ANGPTL3/8 secretion, and these reductions were blocked with the GCGR antagonist antibody.
conclusionsTogether, these results suggest that the GCGR agonism of retatrutide could lead to reduced circulating ANGPTL3/8 concentrations, which may then contribute to decreases in TG and LDL-C levels.
