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
Marine sponges constitute a recognized source of metabolites with potential antibacterial activity. In the present study, the antibacterial activity of the marine sponge Suberites aff. latus from Ica, Peru, was evaluated. Lyophilized sponge samples were extracted using dichloromethane:methanol (1:1), and fractionated by solid-phase extraction into seven fractions (F1-F7), ranging from aqueous to organic polarity. The minimum inhibitory concentration was determined against Gram-positive/negative bacterial strains from the ATCC (American Type Culture Collection) collection. The results showed that the highest activity was observed in fraction F6 of specimen 01J against Klebsiella pneumoniae and Pseudomonas aeruginosa, as well as in fraction F3 of specimen 02J against K. pneumoniae. Qualitative chemical analysis revealed the presence of alkaloids and saponins in the samples. These findings highlight the potential of Suberites aff. latus from the Peruvian coast as a promising source of antibacterial compounds.
