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
Breast cancer (BC) is a common malignant tumor, and circular RNA-trefoil factor 1 (circ-TFF1; hsa_circ_0061825) has been found to be highly expressed in BC tissues and cells and is associated with the poor prognosis of BC patients. However, the interaction between circ-TFF1 and microRNA in BC has not been studied. Quantitative real-time PCR was used to detect the expression of circ-TFF1, miR-129-2-3p, and interleukin (IL)-1 receptor-associated kinase 1 (IRAK1). Through the detection of cell proliferation, migration, invasion, tube formation, and apoptosis, cell function was assessed. The expression levels of angiogenesis-related proteins were detected by western blot. The interaction between miR-129-2-3p and circ-TFF1 or IRAK1 was verified by dual-luciferase reporter assay and RNA immunoprecipitation assay. Xenotransplantation experiments were used to confirm the function of circ-TFF1 in vivo. Circ-TFF1 and IRAK1 were significantly high expressed in BC tissues and cells. Silencing of circ-TFF1 reduced the proliferation, migration, invasion and tube formation, while increased the apoptosis of MDA-MB-361 and SK-Br-3 cells. MiR-129-2-3p was a target of circ-TFF1. Silencing of circ-TFF1 inhibited the malignant behavior of BC cells by releasing miR-129-2-3p. In addition, IRAK1 was a target of miR-129-2-3p. Overexpression of IRAK1 partially restored the inhibitory effect of miR-129-2-3p on cell progression. Animal experiments confirmed the anti-tumor effect of circ-TFF1 knockdown in vivo. Circ-TFF1 regulated the expression of IRAK1 by sponging miR-129-2-3p, thereby, promoting the development of BC. These data provided a novel targeted therapy for BC.
