: The first version of the study protocol was approved by the Peking University First Hospital Institutional Review Board (IRB) (2018[268]) in December of 2018. Any protocol modifications will be submitted for the IRB review and approval.To reduce the risk of infected COVID-19, the follow-up visits were changed to online visits by WeChat during the pandemic period. For each online visit, data regarding any exacerbations experienced during the past 3 months will still be collected, and the asthma assessment scales will still be conducted. However, the data from the physical examinations, lung function tests (bronchodilator reversibility tests) and FeNO measurements will be missed. These modifications to the protocol have been approved by the Peking University First Hospital IRB.The study will be conducted in accordance with Good Clinical Practice (GCP) requirements and ethical principles outlined in the Declaration of Helsinki.The purposes, procedures, and potential benefits and risks of the study will be explained carefully by investigators with written informed consent. Written informed consent will be obtained from each participant. Personal information and related documents of all participants will be kept strictly confidential. Every participant will be identified by a subject number and a name acronym in the case report form.
