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
Background: MicroRNA-129 (miR-129) is known to promote chemosensitivity of many types of cancer cells. However, the role of miR-129 in acute myeloid leukaemia (AML) is unclear. We predicted that premature miR-129 might interact with circEHBP1, a well-characterized oncogene in bladder cancer, and analyzed the interaction between circEHBP1 and miR-129 in AML. Methods: Expression of circEHBP1 and miR-129 in AML patients before and after adriamycin (ADR) treatment was determined by RT-qPCR. CircEHBP1 distribution in nuclear and cytoplasm fractions of AML cells was determined using a cellular fractionation assay. The direct interaction of circEHBP1 with premature miR-129 was explored with an RNA-RNA pull-down assay. Finally, the role of circEHBP1 in regulating miR-129 maturation was analyzed in overexpression cells by RT-qPCRs. Results: Compared to the controls, AML patients exhibited increased circEHBP1 and premature miR-129 levels but decreased mature miR-129 levels. Altered gene expression was more obvious in ADR resistant group than in ADR sensitive group. CircEHBP1 was detected in both nuclear and cytoplasm fractions of AML cells and directly interacted with premature miR-129. CircEHBP1 overexpression increased premature miR-129 level but decreased mature miR-129 level. In AML cells, circEHBP1 suppressed ADR-induced cell apoptosis and attenuated the enhancing effects of miR-129 on cell apoptosis. More importantly, the role of circEHBP1 in regulating cell apoptosis was more obvious in ADR resistance cells. Conclusion: CircEHBP1 may suppress miR-129 maturation to increase the chemoresistance of cancer cells to ADR in AML.
