Association rules for falls-related adverse events based on JADER database between April 2004 and November 2016. Support and lift were visualized using the R-extention package arulesViz which implements novel visualization techniques to explore association rules. The arguments of plot in the arulesViz were set as follows: method = “graph,” measure = “support,” shading = “lift.” The measures of support were used in visualization as area of circle. The measures of lift were used for the shading of color of the circle
