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
backgroundThe escalating threat of antifungal resistance stemming from Trichosporon asahii (T. asahii) biofilms necessitates the pursuit of innovative therapeutic strategies. Among these approaches, 5-aminolevulinic acid (ALA) photodynamic therapy (PDT), an emerging therapeutic modality, has exhibited promising potential in eradicating T. asahii biofilms.
methodsThe inhibitory activity was evaluated by confocal laser scanning microscopy. To delve deeper into the efficacy of ALA-PDT in eliminating T. asahii biofilms, we conducted a comprehensive transcriptional analysis utilizing transcriptome sequencing.
resultsALA-PDT demonstrated a profound inhibitory effect on the viability of T. asahii biofilms. Our investigation unveiled 2720 differentially expressed genes following exposure to ALA-PDT. Subsequent meticulous scrutiny allowed for the annotation of genes with a ≥ twofold change in transcription, focusing on Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathways. Particularly noteworthy were the upregulated genes associated with oxidation-reduction processes, oxidoreductase activity, and catalytic activity. Conversely, the downregulated genes were linked to ATP binding, protein phosphorylation, and protein kinase activity. Additionally, we observed a surge in the transcription of genes that may be involved in oxidative stress (e.g., A1Q1_05494) as well as genes that may be involved in morphogenesis and biofilm formation (e.g., A1Q1_04029, A1Q1_01345, A1Q1_08069, and A1Q1_01456) following ALA-PDT treatment.
conclusionsOur findings underscore the substantial impact of ALA-PDT on the transcriptional regulation of genes related to oxidative stress, morphogenesis, and biofilm formation, paving the way for novel therapeutic avenues in combating T. asahii biofilms.
