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
The increasing incidence of antibiotic-resistant Staphylococcus aureus infections has created a critical need for alternative therapeutic agents that are effective and safe. Antimicrobial peptides are considered attractive candidates in this context. A scorpion peptide derivative, designated HP-H1K8, was designed in this study and was then found to possess potent activity against methicillin-resistant S. aureus (MRSA), coupled with low toxicity and high serum stability. The mechanism of action was identified as bacterial membrane disruption. In a mouse model of MRSA-induced skin infection, the topical application of HP-H1K8 was shown to significantly reduce bacterial load in the wound and enhance the healing process. Additionally, the peptide was not prone to inducing bacterial resistance. It is concluded that HP-H1K8 represents a potent topical agent for the treatment of skin infections caused by drug-resistant S. aureus.
