TCDD-elicited effects on liver, serum, and adipose lipid composition in C57BL/6 mice.
Article in Toxicological sciences : an official journal of the Society of Toxicology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 44 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
The aryl hydrocarbon receptor (AhR) mediates alterations in hepatic lipid composition elicited by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). In order to further investigate the effects of TCDD, liver, serum, and gonadal white adipose tissue (gWAT) fatty acid methyl esters (FAMEs) and lipids were examined in fasted 4-week-old female mice orally gavaged with 30 µg/kg TCDD at 24, 72, and 168 h postdose. Mean hepatic FAME levels increased (236.7 µmol/g in controls compared with 392.2 µmol/g in TCDD treated) with minimal changes in gWAT and serum. In the liver, TCDD decreased saturated fatty acids (SFAs 16:0, 18:0, 20:0, and 22:0) and increased monounsaturated fatty acids (MUFAs 16:1n7, 18:1n9, and 20:1n9). Hepatic polyunsaturated fatty acids (PUFAs) 20:2n6, 20:3n6, 18:3n3, and 22:5n3 also increased, whereas 20:4n6 and 22:6n3 levels decreased. gWAT PUFAs 20:2n6 and 20:3n6 exhibited modest increases, whereas serum 18:0 decreased and 18:1n9 increased. Serum analyses also identified a ~25% decrease in total cholesterol (CHOL), low-density lipoprotein (LDL), and high-density lipoprotein following TCDD treatment. The decrease in serum CHOL was consistent with the induction of hepatic reverse CHOL transport genes Lcat (2.0-fold), Apoa1 (1.7-fold), and Ldlr (3.6-fold), and the repression of CHOL biosynthesis genes Hmgcs1 (-2.1-fold) and Hmgcr (-2.3-fold). In addition, TCDD decreased serum Apob100 (4.4-fold) and Apob48 (2.2-fold) protein levels, suggesting serum lipid clearance and decreased hepatic efflux. Collectively, the TCDD-elicited decreases in serum lipid levels are consistent with AhR-mediated enhancement of dietary fat distribution to the liver.
