Panels A and B show line graphs of SCR trends in oral drugs and parenteral drugs, respectively. The median SCRs of oral branded drugs were higher than 1, but those of generic drugs were lower than 1. Panels C and D show boxplots of monthly SCRs from 2015 to 2017. A significant difference (P < 0.001) was observed in oral drugs, but not in parenteral drugs (P = 0.183).
