To the Editor:Psoriasis is a common chronic immunemediated systemic inflammatory disease[1]characterized by irritating skin erythema,reduced quality of life,and associated systemic diseases including cardiovascular disease,diabetes,and metabolic syndrome.In 2017,0.5%of China’s population was diagnosed with psoriasis.[2]To improve the overall diagnosis and treatment level of psoriasis in China,the National Clinical Research Center for Skin and Immune Disease launched a national collaborative project called the Psoriasis Standardized Diagnosis and Treatment Center(also named Psoriasis Center)project,[3]in which the first national real-world big data collection platform,Psoriasis Center Registry,was established with more than 300 medical centers across China by 2022.This study aimed to update the current general characteristics and treatment distribution of patients with psoriasis in China by describing the registry data at enrollment. 展开更多
