Figure 2.
Map for keywords in adherence research, 2000–2005.
The size of nodes indicates the keywords centrality, and the thickness of the lines indicates the co-occurrence frequency of keywords pairs.
Figure 3.
The decomposition maps for keywords in adherence research, 2000–2005.
The size of nodes indicates the keywords centrality, and the thickness of the lines indicates the co-occurrence frequency of keywords pairs. The thresholds of co-occurrence frequency in map a ,b and c is ≥15, ≥10 and ≥5, respectively.
Figure 4.
The decomposition maps for keywords in adherence research, 2006–2010.
The size of nodes indicates the keywords betweenness centrality, and the thickness of lines indicates the co-occurrence frequency of keywords pairs. The thresholds of co-occurrence frequency in map a ,b and c are ≥20, ≥15 and ≥10, respectively.
