Selection and screening of bacteria from African nightcrawler, Eudrilus eugeniae (Kinberg, 1867) as potential probiotics in aquaculture.
Article in World journal of microbiology & biotechnology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Earthworms are used as an alternative protein source in aquaculture. These organisms serve as an ideal and favorable site for bacterial growth and activity. Hence, in our present study, we isolated and screened potential probiotic bacteria from African nightcrawler (Eudrilus eugeniae). Among 45 bacterial isolates, four (ANSCI9, BFAR9, RM3, and RM10) were selected based on their hydrophobicity, hydrolytic enzyme production, pH and fish bile tolerance, aggregation, and antimicrobial properties. The selected isolates showed good hydrophobicity (≥ 30%) and enzyme production (≥ 10 mm clearing zones), tolerance to pH and fish bile, and inhibitory properties against pathogenic microorganisms. The isolates were identified as Bacillus sp. RM3 (MH919306), Bacillus sp. RM10 (MH919308), Bacillus sp. ANSCI9 (MH919310) and Bacillus sp. BFAR9 (MH919302). These isolates were individually incorporated in the diets of Nile tilapia (Oreochromis niloticus) fingerlings for 14 days to assess their biosafety. The results showed that the survival rates in all treated groups (98.75 ± 2.5 to 100.00 ± 0.0%) were not significantly different (P < 0.05) from the control group (commercial diet) (96.25 ± 2.5%), suggesting that isolates have no adverse effect on the host. This study revealed the presence of potential probiotic microorganisms in E. eugeniae that are beneficial to the aquaculture industry.
