CANCER, EVENTS, HYPERTENSION, DIABETES
We collected participants' medical records, from the enrollment date to October 1, 2021. We first extracted the demographic information of each subject from their health records, including their gender, age (y), systolic and diastolic pressure (mmHg), medical history, such as hypertension, diabetes, and cancer, current drugs, whether the patient was taking antiplatelet or nonsteroidal anti-inflammatory agents (NSAIDs), CHAHow and when patients would revisit their GPs were determined by the subjects themselves after considering suggestions from their GPs. We extracted data on AF treatment from the subjects' medical records after the follow-up. The data collected included anticoagulants they used, INR values of patients with warfarin, and adverse clinical events during the follow-up. The occurrence of these events was identified according to their medical records, diagnostic records, and any related available auxiliary examinations. For some information that was not accessible via the Internet or due to loss to follow-up, data collection was performed by contacting the patients via telephone. At the end of the study, we interviewed the GP in the AF special consulting room of the software group to inquire about the acceptance of the CDSS and some rational improving ideas about the CDSS and the next cluster-randomized controlled trial. The interview lasted approximately 20 minutes. The interview was recorded (by audio and verbally) after obtaining informed consent from the GP. Two researchers summarized the conversations and independently extracted the key information related to the study. Disagreements were resolved through discussion or by a third researcher.For subjects with new oral anticoagulants (NOACs), loss to follow-up was defined as the last follow-up visit date which was at least 12 months before the ending date (October 1, 2021). For patients receiving warfarin, that was defined as the last follow-up visit date was at least 1 month before the ending date [
