Association between nailfold capillaroscopy abnormalities and autoimmune disease in pediatric populations.

Objective: Time to diagnosis of autoimmune disease in pediatric populations can take years but nailfold capillaroscopy (NFC) may identify early signs of autoimmune disease. The aim of this study is to assess the association between nailfold capillary abnormalities and autoimmune disease in children.

Methods: A systematic search of PubMed, EMBASE, and Scopus was performed to identify all studies published before March 17, 2021.
