Dossier d'\u00e9tudes<\/h2>
Tous les participants se sont am\u00e9lior\u00e9s apr\u00e8s le resurfa\u00e7age au laser. Ce changement avant\/apr\u00e8s ne peut pas \u00eatre attribu\u00e9 \u00e0 GHK-Cu car la proc\u00e9dure elle-m\u00eame \u00e9tait partag\u00e9e par les deux groupes.<\/p>

R\u00e9sultats en contexte<\/h2>
Le seul signal signal\u00e9 entre les groupes figurait dans le questionnaire du patient. Avec les r\u00e9sultats 13 et plusieurs crit\u00e8res d\u2019\u00e9valuation, ce r\u00e9sultat doit \u00eatre trait\u00e9 comme exploratoire plut\u00f4t que pr\u00e9sent\u00e9 comme une preuve de r\u00e9paration des rides.<\/p>
Les recherches ant\u00e9rieures sur les plaies incluent des mod\u00e8les animaux. Ces exp\u00e9riences peuvent soutenir des questions m\u00e9canistes mais ne peuvent pas se substituer \u00e0 des r\u00e9sultats humains topiques contr\u00f4l\u00e9s.<\/p>

L'\u00e9chantillon \u00e9tait trop petit pour permettre une estimation pr\u00e9cise des effets modestes ou des pr\u00e9judices inhabituels.<\/p>

Les articles examin\u00e9s renvoient \u00e0 des articles \u00e9valu\u00e9s par des pairs, \u00e0 des registres d'essais et \u00e0 des dossiers r\u00e9glementaires, conservent les r\u00e9sultats nuls et les limites des \u00e9tudes, et distinguent les interventions publi\u00e9es des documents du catalogue. Le dessin assist\u00e9 par AI peut \u00eatre utilis\u00e9 pour la structure\u00a0; les liens vers les sources et les limites des preuves restent visibles. Ce travail ne constitue pas un examen ind\u00e9pendant par des pairs ni un avis m\u00e9dical.","sameAs":["https:\/\/nhdbio.com"],"url":"https:\/\/nhdbio.com\/fr\/author\/qianmiao-technical-team\/"}]}},"_links":{"self":[{"href":"https:\/\/nhdbio.com\/fr\/wp-json\/wp\/v2\/posts\/470","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nhdbio.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/nhdbio.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/nhdbio.com\/fr\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/nhdbio.com\/fr\/wp-json\/wp\/v2\/comments?post=470"}],"version-history":[{"count":2,"href":"https:\/\/nhdbio.com\/fr\/wp-json\/wp\/v2\/posts\/470\/revisions"}],"predecessor-version":[{"id":536,"href":"https:\/\/nhdbio.com\/fr\/wp-json\/wp\/v2\/posts\/470\/revisions\/536"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/nhdbio.com\/fr\/wp-json\/wp\/v2\/media\/635"}],"wp:attachment":[{"href":"https:\/\/nhdbio.com\/fr\/wp-json\/wp\/v2\/media?parent=470"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/nhdbio.com\/fr\/wp-json\/wp\/v2\/categories?post=470"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/nhdbio.com\/fr\/wp-json\/wp\/v2\/tags?post=470"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
