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
The present study aims to investigate the oral therapeutic and molecular role of carotenoid-rich Dunaliella salina powder (DSP) against 1,2-dimethylhydrazine (DMH)-triggered colon carcinogenesis. In this study, thirty six male Wistar rats were categorized into six distinct groups (G1-G6): G1 group with no intervention, G2 group received only DSP (1000 mg/kg), G3 group received only DMH carcinogen (20 mg/kg), and G4-G6 group received both DMH and DSP at various phases (pre-initiation, post-initiation and entire phases) for 32 weeks. Body weight, tumor incidence, tumor volume, histopathological examination, antioxidants, and detoxification enzymes activities were analyzed in the experimental rats. In addition, the protein expression profile of components involved in the Wnt/β-catenin signaling pathway was determined by western blot analysis. Matrix metalloproteinases (MMP-7 and MMP-9), proliferation marker (PCNA), and pro-apoptotic (Bcl-2 and Bax) proteins were analyzed using immunohistochemistry. Colorimetric assay was used to determine the levels of anti-inflammatory (iNOS and COX-2) and apoptotic proteins (Caspase-3 and Caspase-9). Results showed that concomitant administration of DSP with DMH significantly reduced tumor progression and prevented colon carcinogenesis in rats. However, treatment with DSP before or after DMH exposure did not significantly prevent colon carcinogenesis. DMH and DSP treatment group showed increased activities of antioxidant enzymes with significant reduction in the oxidative stress. Additionally, the detoxification enzymes and colonic histopathology of those rats were restored to that of control rats. The administration of DSP to rats exposed to DMH exhibited antitumor effects via inhibition of the Wnt/β-catenin signaling pathway with induced apoptosis through the Bcl-2/Bax/caspases signaling cascades. Moreover, the same group also showed significant anti-inflammatory activity via regulating iNOS and COX-2 biomarkers. Our findings revealed molecular chemopreventive activity of carotenoid-rich DSP through regulating Wnt/beta-catenin and intrinsic apoptotic pathways. Thus, DSP is propound to function as a potent antioxidant, anti-proliferative, and anti-inflammatory therapeutic agent against colon carcinogenesis.
