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
backgroundColorectal cancer (CRC) is the third most common cancer worldwide, with liver metastasis being the leading cause of mortality. De novo fatty acid synthesis plays a critical role in CRC progression and metastasis. Bufalin, a cardiotonic steroid isolated from toad skin, has demonstrated anticancer activity in multiple preclinical models. However, the mechanisms underlying its suppression of CRC metastasis and modulation of fatty acid synthesis remain to be elucidated.
methodsThe effects of bufalin on CRC cell proliferation, migration, and apoptosis were assessed via colony formation, wound healing, and flow cytometry assays. Transcriptome analysis identified bufalin-affected pathways, with changes in gene and protein expression. FASN protein levels were quantified using ELISA.
resultsBufalin inhibited proliferation and migration of CRC cells and induced the apoptosis of LoVo and HCT8 cells. Transcriptome analysis highlighted lipid metabolism pathways as potential mediators of bufalin's anti-metastatic activity. Notably, bufalin reduced the expression of fatty acid synthase (FASN) and suppressed CRC metastasis. In vivo experiments demonstrated that bufalin attenuated CRC progression and liver metastasis by inhibiting de novo fatty acid synthesis through the PI3K/AKT-mediated SREBP1/FASN pathway.
conclusionsBufalin inhibits de novo fatty acid synthesis via the PI3K/AKT-mediated SREBP1/FASN pathway, suppressing CRC progression and liver metastasis.
