Article in Tumour biology : the journal of the International Society for Oncodevelopmental Biology and Medicine, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 11 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
Cancerous inhibitor of protein phosphatase 2A (CIP2A) is a recently identified human oncoprotein that can stabilize some proteins by inhibiting degradation mediated by protein phosphatase 2A (PP2A), and its level in cancer is associated with resistance to chemotherapy. However, whether CIP2A could increase chemoresistance of prostate cancer (PCa) cells to chemotherapeutic agent cabazitaxel remains unclear. To determine whether CIP2A serves as a potential therapeutic target of human PCa, we utilized small interference RNA (siRNA) to knock down CIP2A expression in human PCa cells and analyzed their phenotypic changes. The data demonstrated that CIP2A was significantly elevated in mCRPC cell lines C4-2 and ARCaP(M) at both the mRNA and protein levels. CIP2A silencing led to decreased proliferation and enhanced chemosensitivity and apoptosis to cabazitaxel in human PCa cells, as well as reduced Akt phosphorylation. Our data suggesting critical roles of CIP2A in PCa cells chemoresistance to cabazitaxel and raising the possibility of CIP2A inhibition as a promising approach for chemosensitization of metastatic castration-resistant prostate cancer (mCRPC).
