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
backgroundOvarian cancer (OC) is a highly malignant gynecological tumor with poor current treatment effects. Telomerase reverse transcriptase (TERT) is an important component of telomerase and plays an important role in the progression of ovarian cancer. Quercetin(QR) has been shown to inhibit the cell cycle and induce the apoptosis in various types of tumors. However, the mechanism of quercetin in ovarian cancer and whether it can be applied in the treatment of ovarian cancer has not been fully understood.
resultsOC cells were intervened with QR in vitro and it was found that QR only inhibited the cell cycle but not induced cell apoptosis. By conducting network pharmacology, proteomics and TCGA-OV database analysis, we found that QR inhibited the cell cycle by binding to P53 and P21. However, in this study, overexpressed TERT in OC could bind to P53 and inhibit the binding of QR to P53, failing to induce tumor cell apoptosis. After TERT was knocked down, QR significantly suppressed the cell cycle of OC cells and induced apoptosis.To realize high drug delivery efficiency and drug targeting to improve the effect of inhibiting OC, we designed and prepared RGD-MSN/QR/shTERT nanoparticles for the combined administration of QR and shTERT. As confirmed by the in vivo experiments, RGD-MSN/QR/shTERT possessed good targeting ability and significant OC inhibiting effect, with no adverse reactions, and improved the survival benefits.
conclusionsThis study demonstrated the mechanistic and therapeutic advantages of combining QR with shTERT in the treatment of OC. Based on this mechanism, we synthesized the novel nanoparticles (RGD-MSN/QR/shTERT) and verified the favorable OC inhibiting effect in vivo, providing a novel strategy for the treatment of OC.
