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 secreted human protein SLURP-2 is a regulator of epithelial homeostasis, which enhances the viability and migration of keratinocytes. The targets of SLURP-2 in keratinocytes are nicotinic and muscarinic acetylcholine receptors. This work is devoted to the search for the SLURP-2 functional regions responsible for enhancing keratinocyte viability and migration. We produced synthetic peptides corresponding to the SLURP-2 loop regions and studied their effect on the viability and migration of HaCaT skin keratinocytes using the WST-8 test and scratch-test, respectively. The highest activity was exhibited by a loop II-mimicking peptide that enhanced the viability of keratinocytes and stimulated their migration. The peptide activity was mediated by interactions with α7- and α3β2-nAChRs and suppression of the p38 MAPK intracellular signaling pathway. Thus, we obtained new data that explain the mechanisms underlying SLURP-2 regulatory activity and indicate the promise of further research into loop II-mimicking peptides as prototypes of wound healing drugs.
