A hedgehog cathelicidin-derived peptide exhibits antiviral activity against herpes simplex virus type 1 infection.

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
Herpes simplex virus type 1 (HSV-1) is a widespread infectious virus that poses a substantial public health burden. With no specific curative therapy available and current antivirals providing only symptomatic relief, the development of new effective antiviral agents remains imperative. Antimicrobial peptides, particularly cathelicidins, are key immune effector molecules with antiviral and immunomodulatory properties. In this study, we found that European hedgehog skin extract (HSE) exhibited potent anti-HSV-1 activity, prompting us to investigate the contribution of the cathelicidin peptide CathEE. Based on this observation, three CathEE-derived antiviral peptides (CathEE-1, CathEE-2, and CathEE-3) were designed and further optimized to yield CathEE-2a and CathEE-2b. Notably, CathEE-2a displayed pronounced antiviral activity
