Article in Aesthetic plastic surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06999408 (A Prospective, 8-Month, Randomized Pilot Study of TargetCool™ Cryo-Modulation and BENEV Exosome Regenerative Complex+® for Hair Density Enhancement in Adults With Non-Scarring Hair Thinning), which is not on this map. Cited by 22 papers, 1 of them a synthesis that pooled it.

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.

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.

Abstract

objectiveHarnessing the regenerative capabilities of stem cell-derived exosomes holds great promise for developing novel hair growth therapies, offering hope for individuals experiencing hair loss or alopecia. This aimed to elucidate the effect of "foreskin-derived mesenchymal stromal cells derived exosome" injection into the scalp on hair density in patients with androgenetic alopecia and the contribution of this treatment on patient satisfaction.

methodThis prospective study included 30 male patients, aged between 22 and 65, with hair type III-VI according to the Norwood-Hamilton scale. Characterization of the stem cell exosomes was performed with the nanoparticle tracking analysis (NTA), hair densities were calculated via digital imaging analysis, and patient satisfaction was questioned with a modified survey.

resultsNTA results showed a characteristic distribution of peaks for exosomes 139.7 ± 2.3 nm in diameter. A statistically significant increase in hair density was observed in the 4th and 12th weeks after treatment (p < 0.05). Patient-reported satisfaction revealed a statistically significant difference in the answers given in the 12th week compared to the 4th week (p < 0.05). No side effects or complications were observed after exosome injection.

conclusionForeskin-derived mesenchymal stromal cells derived exosome injection increased hair density, with sustained patient satisfaction throughout the study. The exosome application resulted in no side effects. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.
