- Note: The number of days in the last column between the first date of “release dates of relevant policies or guidelines” and the first date of “stages of rising heat for clusters of research topics” is taken from the average of the date interval between the two waves of each cluster. Among them, the period of rising heat of terms related to children, pregnant women, and Chinese medicine is included in the period of concentrated promulgation of related policies/programmes; thus, only the time difference between the period of concentrated promulgation of the first wave of related policies/programmes and the period of concentrated heat of related terms is counted
