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
Prostate cancer remains the most prevalent malignancy diagnosed in men worldwide. Epithelial cell transforming sequence 2 (ECT2) is an oncogene involved in the progression of human tumors. The present study aimed to explore the involvement of ECT2 in prostate cancer and its participation in the malignant progression of prostate cancer. ECT2 expression in prostate cancer cell lines was examined via reverse transcription-quantitative PCR and western blotting. The effects of knockdown of ECT2 expression in PC-3 cells on cellular biological behaviors, including proliferation, migration and invasion, were examined using Cell Counting Kit-8, colony formation, wound healing and Transwell assays. The glycolysis level was determined based on the lactate release, glucose uptake, oxygen consumption rate and extracellular acidification rate. The binding relationship between ECT2 and ETS1 was verified using luciferase reporter and chromatin immunoprecipitation assays. The results indicated that ECT2 was highly expressed in prostate cancer cell lines. Knockdown of ECT2 expression could inhibit cell proliferation, migration, invasion and glycolysis. In addition, the transcription factor ETS1 could directly bind to the ECT2 promoter and positively regulate ECT2 expression. These data were combined with the results of rescue experiments and demonstrated that the inhibitory effects of the knockdown of ECT2 expression on the malignant behavior and glycolysis of prostate cancer cells were partially reversed by ETS1 overexpression. In conclusion, ETS1 induced transcriptional upregulation of ECT2 and enhanced the malignant biological behaviors of prostate cancer cells, thereby promoting the progression of prostate cancer. This evidence provides a theoretical basis for the treatment of prostate cancer.
