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
objectivesTo investigate the mechanism of cephaeline for suppressing malignant biological behaviors of colorectal cancer (CRC).
methodsNetwork pharmacology was employed to identify the core targets and signaling pathways of cephaeline in CRC treatment. The binding between the key targets of CRC and cephaeline was simulated using molecular docking. CCK-8 assay was used to assess the viability of HCT116 and DLD-1 cells treated with 2-32 nmol/L cephaeline for 24, 48, and 72 h to determine the optimal treatment condition. The effects of cephaeline treatments (at 2 and 4 nmol/L in HCT116 cells and at 4 and 8 nmol/L in DLD-1 cells) for 48 h on cell proliferation, migration, invasion, epithelial‑mesenchymal transition (EMT), apoptosis, and expressions of RAS signaling pathway proteins were evaluated using colony-forming assay, wound healing assay, Transwell assays, and Western blotting.
resultsNetwork pharmacology analysis suggested that cephaeline inhibited CRC mainly by regulating the targets such as MAPK, VEGFA, and PDGFRB and modulating the Rap1, Ras, cAMP, and PI3K-Akt signaling pathways. Molecular docking results showed that the binding energies of cephaeline with PDGFRB and MAPK1 were less than -5 kcal/mol, indicating spontaneous and stable binding between them. In HCT116 and DLD-1 cells, treatment with cephaeline concentration-dependently suppressed the cell viability, proliferation, migration, and invasion, downregulated the expressions of PCNA, MMP9, VEGF-C, BCL-2, N-cadherin, vimentin, VEGF-A, PDGFRB, MYC, and MAPK1, and upregulated the expression levels of E-cadherin and BAX.
conclusionsCephaeline suppresses malignant biological behaviors of CRC possibly by regulating the RAS signaling pathway.
