1 · What the graph read from it

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.

2 · The registry

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

Fungal infections in humans are increasing worldwide and are currently mostly treated with a relative limited set of antifungals. Resistance to antifungals is increasing, for example, in Aspergillus fumigatus and Candida auris, and expected to increase for many medically relevant fungal species in the near future. We have developed and patented a set of cathelicidin-inspired antimicrobial peptides termed 'PepBiotics'. These peptides were initially selected for their bactericidal activity against clinically relevant Pseudomonas aeruginosa and Staphylococcus aureus isolates derived from patients with cystic fibrosis and are active against a wide range of bacteria (ESKAPE pathogens). We now report results from studies that were designed to investigate the antifungal activity of PepBiotics against a set of medically relevant species encompassing species of Aspergillus, Candida, Cryptococcus, Fusarium, Malassezia, and Talaromyces. We characterized a subset of PepBiotics and show that these peptides strongly affected metabolic activity and/or growth of a set of medically relevant fungal species, including azole-resistant A. fumigatus isolates. PepBiotics showed a strong inhibitory activity against a large variety of filamentous fungi and yeasts species at low concentrations (≤1 μM) and were fungicidal for at least a subset of these fungal species. Interestingly, the concentration of PepBiotics required to interfere with growth or metabolic activity varied between different fungal species or even between isolates of the same fungal species. This study shows that PepBiotics display strong potential for use as novel antifungal compounds to fight a large variety of clinically relevant fungal species.
