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
PPARgamma agonist DIM-Ph-4-CF(3), a template for RXRalpha agonist (E)-3-[5-di(1-methyl-1H-indol-3-yl)methyl-2-thienyl] acrylic acid: DIM-Ph-CF(3) is reported to inhibit cancer growth independent of PPARgamma and to interact with NR4A1. As both receptors dimerize with RXR, and natural PPARgamma ligands activate RXR, DIM-Ph-4-CF(3) was investigated as an RXR ligand. It displaces 9-cis-retinoic acid from RXRalpha but does not activate RXRalpha. Structure-based direct design led to an RXRalpha agonist.1-Di(1H-indol-3-yl)methyl-4-trifluoromethylbenzene (DIM-Ph-4-CF(3)) is reported to inhibit cancer cell growth and to act as a transcriptional agonist of peroxisome proliferator-activated receptor gamma (PPARgamma) and nuclear receptor 4A subfamily member 1 (NR4A1). In addition, DIM-Ph-4-CF(3) exerts anticancer effects independent of these receptors because PPARgamma antagonists do not block its inhibition of cell growth, and the small pocket in the NR4A1 crystal structure suggests no ligand can bind. Because PPARgamma and NR4A1 heterodimerize with retinoid X receptor (RXR), and several PPARgamma ligands transcriptionally activate RXR, DIM-Ph-4-CF(3) was investigated as an RXR ligand. DIM-Ph-4-CF(3) displaces 9-cis-retinoic acid from RXRalpha but does not transactivate RXRalpha. Structure-based design using DIM-Ph-4-CF(3) as a template led to the RXRalpha transcriptional agonist (E)-3-[5-di(1-methyl-1H-indol-3-yl)methyl-2-thienyl]acrylic acid. Its docked pose in the RXRalpha ligand binding domain suggests that binding is stabilized by interactions of its carboxylate group with arginine 316, its indoles with cysteines 269 and 432, and its 1-methyl groups with hydrophobic residues lining the binding pocket. As is expected of a selective activator of RXRalpha, but not of RARs and PPARgamma, this RXRalpha agonist, unlike DIM-Ph-4-CF(3), does not appreciably decrease cancer cell growth or induce apoptosis at pharmacologically relevant concentrations.
