Epidemiology of Mixed Connective Tissue Disease, 1985–2014: A Population‐Based Study

Abstract

This study was the first population-based study of MCTD to provide a complete picture of epidemiology and clinical characteristics of MCTD. MCTD occurred in about 2 persons per 100,000 per year. Evolution to other connective diseases occurred infrequently and the mortality was not affected.
