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
backgroundVacuole and mitochondria patch (vCLAMP) protein Mcp1 is crucial in eukaryotic cells response to environmental stress, but the mechanism of Mcp1 in Saccharomyces boulardii (S. boulardii) against pathogenic fungi is unclear.
resultsThis work first explored the role of Mcp1 in S. boulardii against Candida albicans (C. albicans). The results showed that Mcp1 located on the vacuolar and mitochondrial membrane of S. boulardii. Overexpression of Mcp1 inhibited the adhesion and hyphal formation of C. albicans in vitro. The mice model of intestinal infection revealed that WT-pGK1-MCP1 mutant enhanced the ability of S. boulardii antagonize C. albicans infecting gut. High performance liquid chromatography-mass spectrometry analysis demonstrated that overexpressing Mcp1 promoted the production of 2-phenylethanol. The latter is a secondary metabolite of S. boulardii, and can inhibit the adhesion and biofilm formation of C. albicans. The reverse transcription polymerase chain reaction and western blotting results confirmed Mcp1 promoted the production of 2-phenylethanol by regulating the expression level of Aro10. Notably, RNA-sequencing and Gene Ontology enrichment analyses showed that 2-phenylethanol impaired the oxidative stress response of C. albicans.
conclusionThis work reveals the critical role of Mcp1 in S. boulardii against C. albicans by regulating 2-phenylethanol metabolism, which provide a theoretical basis for S. boulardii as antifungal biologic therapy to prevent and treat of Candida infection.
