Article in Translational cancer research, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundNeural precursor cell-expressed, developmentally downregulated protein 9 (NEDD9) is an invasion and metastasis-related gene. It has been proven to be highly expressed and closely associated with tumor proliferation and invasion in several types of human cancers including pancreatic adenocarcinoma. The present study was aimed to investigate and characterize the efficacy of silencing NEDD9 by lentivirus-delivered shRNA in pancreatic cancer (PC) BxPC-3 cells
methodsFive kinds of PC cell lines were used to determine the cell line which expressed NEDD9 the most with qRT-PCR and western blotting. Then, we transduced the lentivirus-delivered NEDD9 shRNA into the human PC BxPC-3 cells to obtain a stable cell line expressing shRNA targeting NEDD9. NEDD9 mRNA and protein expression were measured by qRT-PCR and western blotting, respectively. Cell proliferation, migration, and invasion were assessed by cell colony formation, scratch wound healing, and Transwell assays, respectively. Mouse tumor xenografts were established by injecting tumor cells into the right flank of BALB/c nude mice. The effects of silencing NEDD9 on the growth of BxPC-3 cells
resultsAmong 5 kinds of PC cell lines, BxPC-3 cells were selected as the most suitab to carry out the following experiment. Transduction of lentivirus-delivered NEDD9 shRNA efficiently reduced NEDD9 expression in pancreatic adenocarcinoma BxPC-3 cells. Silencing NEDD9 by RNAi inhibited proliferation, migration, and invasion of BxPC-3 cells in cell culture. Importantly, it significantly reduced the growth of BxPC-3 cells in mouse xenografts.
