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

Atopic dermatitis (AD) is a chronic immune-mediated inflammatory skin disease. An overgrowth of Staphylococcus aureus (S. aureus) and decreased microbial diversity is apparent in 70%-90% of AD patients. SA.100 is a recombinant endolysin targeting S. aureus that might be a novel treatment for patients with mild-to-moderate AD. To test safety, pharmacodynamics and efficacy of SA.100 a double-blind, randomized, vehicle-controlled trial in 53 subjects with mild-to-moderate AD was performed. Patients were randomized equally to topical SA.100 or vehicle with stratification for S. aureus positivity. SA.100 was safe and well tolerated. No reduction of S. aureus and no changes in microbiome features were seen after 2 weeks of treatment. Additionally, no statistically significant changes in clinical or patient-reported outcomes were observed compared to vehicle. In conclusion, topical SA.100 was safe and well tolerated in patients with mild-to-moderate AD, but our findings do not support short-term clinical use.
