The notable advances in interstitial lung disease (ILD) published in Chinese and international authoritative journals from November 2022 to October 2023 were systematically reviewed in our annual review. The year 2023 brought significant advances about mechanism, diagnosis and treatment of idiopathic pulmonary fibrosis, connective tissue diseases associated ILD, sarcoidosis, progressive pulmonary fibrosis and rare ILDs. The related global and/or Chinese commentaries and guidelines were also reviewed in our paper.
