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
LncRNAs are associated with malignancies with their tumor suppressor/oncogenic properties. Although many studies are conducted related to the mechanism of action for dasatinib and ponatinib in chronic myeloid leukemia (CML), their comparative effects on lncRNA expressions are largely unknown. Hence, we aimed to define the lncRNAs involved in the treatment of CML with dasatinib and ponatinib. We measured the cytotoxicities of dasatinib/ponatinib with CCK-8 assay and identified differentially expressed lncRNAs (DEL) by qRT-PCR. We determined the principal functions of DELs by Ingenuity Pathway Analysis (IPA) and performed gene ontology (GO) analysis for apoptosis and anti-proliferation-related lncRNAs. Apoptotic and anti-proliferative activities of dasatinib/ponatinib were confirmed by flow-cytometry. In K562 cells, dasatinib/ponatinib re-regulated lncRNAs which were dysregulated in leukemia. DELs after treatment (forty with dasatinib, thirty-seven with ponatinib) were related to increased cell death; decreased cell viability, proliferation, tumor growth, invasion, migration. Dasatinib-mediated network was related to cancer, hematological disease while ponatinib-mediated network was associated with cancer, cell death/survival, cell-to-cell signaling/interaction. Both treatments predicted activation of IFNγ, IL1β, TNF as upstream regulators, specially this effect was higher in dasatinib. Comparison analysis showed that ponatinib was predicted more effective in cell death of tumor cell line than dasatinib. We confirmed that ponatinib was more potent than dasatinib to induce apoptosis and inhibit proliferation of CML cells, in consensus with IPA and GO analysis results. LncRNAs are specifically involved in anti-leukemic activities of dasatinib and ponatinib. Our findings will contribute to understanding signalization occurring in CML cells after standard treatments.
