Down-expression of poly(ADP-ribose) polymerase in p53-regulated pancreatic cancer cells.
Article in Oncology letters, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
The present study investigated whether poly(ADP-ribose) polymerase (PARP) has an effect on p53-regulated pancreatic cancer. The results of the present study demonstrated that the expression of PARP affects proliferation and apoptosis of pancreatic cancer cells. Olaparib was used to suppress the expression level of PARP-1 in PanC-1 cells. Decreased expression of PARP-1 suppressed cell proliferation and induced apoptosis of PanC-1 cells when compared with controls. Furthermore, decreased expression of PARP-1 resulted in decreased levels of pro-caspase-3 expression, increased caspase-3 activity, suppressed B-cell lymphoma 2 (Bcl-2) protein expression and increased p53 protein expression in PanC-1 cells. Subsequently, ataxia telangiectasia mutated (ATM) activity was inhibited alongside down-expression of PARP-1 resulting in significantly decreased cellular viability of PanC-1 cells, increased p53 protein expression, decreased expression of pro-caspase-3, increased caspase-3 activity and suppressed Bcl-2 protein expression, when compared with PARP-1 suppression alone. Overall, the
