Training methods
The offline training group engaged in traditional learning, i.e., by gathering in a specific area where a lecturer presented a slide presentation and content explanations. For the online training group, the lecturer pre-recorded the training information and uploaded it to either the DingTalk or WeChat platforms. The members of this group finished the training on their own within the specified time. The content of the course was the same for both groups and the training duration was 1 h.Two neurology physicians were uniformly trained and qualified prior to conducting the survey. Following on, they conducted the questionnaire survey, and the AD-related knowledge training, and completed the data collection. The quality was controlled by at least one chief neurology physician.
