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
PlK1 has a significant role in the development of breast cancer. Thus, silencing of PlK1 gene may arrest the growth of breast cancer. However, the in vivo stability of PlK1 siRNA after injection remains a challenge to target the specific site. The delivery of siPlK1 RNA via viral vector and amine group-terminated dendrimer is associated with immune reaction and cellular cytotoxicity. Thus, in the present study, hyaluronic acid-functionalized and -thiolated polycaprolactone nanoparticles (SH-HPP NPs) were developed for enhancing the targeting capabilities of siRNA towards human breast cancer cells. NPs displayed size in the range of 180-217 nm, and with sustain and pH-dependent release of siRNA up to 120 h. The in vitro treatments with siRNA-containing NPs showed the high number of necrotic cells and the cell cycle arrest at the G2/M phase. The gene expression analysis depicts the decrease of endogenous PLK1 siRNA expression on MCF-7 cells upon PLK1 NPs treatment. In vitro cytotoxicity experiments demonstrated effective anticancer properties against MCF-7. Finally, in vivo results showed that substantial tumor inhibition was achieved with PLK1 siRNA-containing SH-HPP NPs in comparison of the control group. Hence, HPP NPs have enormous potential for the selective delivery of siRNA, i.e., breast cancer cells.
