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
Advanced metastatic colon cancer is difficult to treat with existing chemotherapy medicines, and hypoxic microenvironment is closely related to angiogenesis and distant metastasis of colon cancer. Quercetin, a natural flavonoid, has been shown anti-tumor effects. The aim of this study is to investigate the effect of quercetin alone or combined with 5-FU on the invasion and metastasis of advanced metastatic or primary colorectal cancer in hypoxic environment. The cytotoxicity of quercetin or/and 5-FU on colon cancer cells using CCK8 assay, Hoechst 33342, flow cytometry and AO staining. The effects of quercetin or/and 5-FU on the migration and invasion were determined by transwell, cell scratching method and murine xenograft models. The potential mechanism was explored by Western blot and immunofluorescent assay. The results revealed quercetin effectively inhibited the invasion and migration of high metastatic advanced colon cancer LOVO cells under hypoxia through the inhibition of ROS and the expression of HIF-1α and PI3K/AKT pathway. Combination of quercetin and 5-FU could promote the inhibition of 5-FU on the invasion and migration of LOVO cells. Moreover, quercetin also significantly inhibited the proliferation of either LOVO cells or HT-29 cells under hypoxia by inducing apoptosis and autophagy, particularly, showing stronger inhibition on HT-29 cells than LOVO cells. In conclusion, quercetin inhibited the invasion and migration of advanced metastatic colon cancer LOVO cells under hypoxia through inhibition of ROS and HIF-1α expression and the downregulation of PI3K/AKT pathway. Moreover, quercetin alone or in combination with 5-FU can effectively inhibit the invasion and migration of high metastatic advanced colon cancer. Quercetin has the potential to be used as an effective anti-colon cancer drug alone or in combination for the clinical treatment of advanced colon cancer.
