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
backgroundSeveral 4,6-diarylpyrimidin-2-amine derivatives show anticancer properties. However, their mode of action is not fully characterized. To develop potent anticancer chemotherapeutic agents, we designed and synthesized 25 4,6-diphenylpyrimidin-2-amine derivatives containing a guanidine moiety.
methodsClonogenic long-term survival assays were performed to screen anticancer compounds. To derive the structural conditions showing good cytotoxicities against cancer cells, quantitative structure-activity relationships (QSAR) were calculated. Biological activities were determined by flow cytometry for cell cycle analysis and by immunoblot analysis for the detection of Aurora kinase A (AURKA) activity. Because 2-(2-Amino-6-(2,4-dimethoxyphenyl)pyrimidin-4-yl) phenol (derivative 12) selectively inhibited AURKA activity from the kinome assay, in silico docking experiments were performed to elucidate the molecular binding mode between derivative 12 and AURKA.
resultsThe pharmacophores were derived based on the QSAR calculations. Derivative 12 inhibited AURKA activity and reduced phosphorylation of AURKA at Thr283 in HCT116 human colon cancer cells. Derivative 12 caused the accumulation of the G2/M phase of the cell cycle and triggered the cleavages of caspase-3, caspase -7, and poly(ADP-ribose) polymerase. The binding energies of 30 apo-AURKA - derivative 12 complexes obtained from in silico docking ranged from -16.72 to -11.63 kcal/mol.
conclusionsDerivative 12 is an AURKA inhibitor, which reduces clonogenicity, arrests the cell cycle at the G2/M phase, and induces caspase-mediated apoptotic cell death in HCT116 human colon cancer cells. In silico docking demonstrated that derivative 12 binds to AURKA well. The structure-activity relationship calculations showed hydrophobic substituents and 1-naphthalenyl group at the R2 position increased the activity. The existence of an H-bond acceptor at C-2 of the R1 position increased the activity, too. Graphical abstract Derivative 12 inhibits Aurora kinase A activity and causes the G2/M phase arrest of the cell cycle.
