Chlorogenic acid suppresses angiogenesis in 4T1 breast tumors

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
Background and purpose: Angiogenesis, as a physiological process, plays a key role in the development of invasive tumors. However, polyphenol compounds such as chlorogenic acid (CGA) can help reduce the risk of metastasis. This study explored the anti-angiogenic properties of CGA in a metastatic tumor model. Experimental approach: Forty female BALB/c mice were randomly divided into 5 groups, including saline, receiving normal saline; breast cancer (BC), receiving 4T1 cells and normal saline; CGA group, receiving CGA solution; PR group, receiving simultaneously 4T1 cells and CGA; treatment group (TM), receiving CGA after tumor induction. The treatment period was 14 days. The anti-angiogenic effects of CGA were examined using the H&E and TB staining in breast, liver, and lung tissues of the metastatic tumor model. Real-time RT- PCR was also conducted to determine the expression of Findings/Results: Histomorphological evaluations demonstrated a significant reduction in the number of all types of breast vessels and many vessels of lung tissue in the TM group compared with the BC group. Also, the diameter of sinusoid capillaries and veins of liver tissue significantly decreased with the administration of CGA compared with the BC group. Moreover, real-time RT-PCR results showed that CGA administration downregulated the expression of Conclusion and implications: CGA plays an important role in inhibiting angiogenesis by decreasing the expression of
