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
Bacterial resistance towards antibiotics has become a major problem worldwide. Bacteria become more resistant towards available antibiotics due to quorum sensing and biofilm formation. Alkaloids exhibited potential anti-bacterial activity. In the present study, the anti-quorum sensing and antibiofilm abilities of gramine (GRM) are evaluated. Gramine, an alkaloid already reported for several biological activities includes antiviral, anti-bacterial and antitumor was evaluated for its inhibition of quorum sensing and biofilm mediated virulence in Pseudomonas aeruginosa. The anti-infective effect of GRM using Caenorhabditis elegans and Galleria mellonella models was determined. Gramine reduced violacein production by 78% in C. violaceum. GRM inhibit 84% biofilm formation in P. aeruginosa. Notably, GRM inhibits several virulence factors (Pyocyanin, Pyoverdine, HCN, Alginate and several others) of P. aeruginosa. Further validation by qRT-PCR showed that GRM significantly downregulated several virulence associated genes. In silico studies revealed the GRM interaction with the three main quorum sensing signal receptors (LasR, RhlR and PqsR) of P. aeruginosa. In vivo anti-infective experiments suggested GRM's protective effect in C. elegans and G. mellonella infection models. Our results suggests that GRM as an effective anti-biofilm and anti-infective agent.
