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
introductionFree fatty acid receptors (FFARs) are G protein-coupled receptors that divide into 4 subtypes; FFAR2 and FFAR3 are activated by short-chain fatty acids, while FFAR1 and FFAR4 - by long-chain fatty acids. Recent studies show the potential involvement of FFARs in the pathophysiology of colorectal cancer (CRC). A decrease in FFAR2 and FFAR4 gene expression is observed in patients with CRC. The aim of our study was to evaluate the anti-cancer effect of FFAR2 and FFAR4 stimulation by selective synthetic agonists in in vitro and in vivo models of CRC. MATERIALS AND
methodsFFAR2 agonist, 4-CMTB, and FFAR4 agonist, GSK137647 were used. Cell viability (CCD 841 CoN and SW-480) was determined after 48 h incubation with tested compounds using MTT assay. Real-time qPCR and Western Blot were used to identify changes in FFARs expression. Migration and invasion were characterized by commercially available tests. Colitis-associated CRC (CACRC) mouse model was induced by azoxymethane and dextran sodium sulfate.
results4-CMTB and GSK137647 significantly reduced cancer cell growth as well as migration and invasion capacities. Both synthetic compounds increased FFAR2 and FFAR4 expression in SW-480 cells. Neither 4-CMTB nor GSK137647 influenced the course of AOM/DSS-induced CACRC in mice, however, 4-CMTB elevated FFAR2 protein expression in mouse tissues.
conclusionWe presented that stimulation of FFAR2 and FFAR4 may inhibit CRC cell viability and migration and that the FFAR2 and FFAR4 expression decreased in CRC can be restored by treatment with respective agonists, indicating new promising pharmacological targets in CRC treatment.
