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
DNA damage response (DDR) that includes cell cycle check points, DNA repair, apoptosis, and senescence is intimately linked with cancer. It shields an organism against cancer development when genomic integrity fails. DNA repair pathways protect the cells from tumor progression caused as a result of DNA damage induced by irradiation or due to chemotherapeutic treatment. Many promising anticancer agents have been identified that target specific DNA repair pathways in response to DNA damage thereby leading to apoptosis. Here we identified a novel bisindole-PBD conjugate that possess potent anticancer activity in breast cancer cells. Further studies aimed at understanding the mechanism of action of the molecule showed its role in DNA damage induced apoptosis via inhibition of DNA repair pathway. Trypan blue and BrdU assay exhibited a dose-dependent effect. Single-stranded DNA damage was observed by COMET assay. In addition DNA damage induced ROS generation with simultaneous activation of ATM and ATR upon compound treatment was observed. Further downregulation of Bcl-XL and activation of Bax showed DNA damage induced apoptosis in MCF-7 and MDAMB-231 cells. In conclusion, it can be summarized that bisindole-PBD conjugate induces DNA damage in a dose dependent (2, 4, and 8 μM) manner by inhibiting the DNA repair genes.
