Data aggregation temporality with respect to date of HCC diagnosis. PMSI data from 1 January 2007 to 31 December 2013 were considered for the study. Only the period from 1 July 2007 to 31 December 2012 was considered to identify a HCC diagnosis (contemporary period of HCC diagnosis). The individual sample shows the case for a patient with a HCC diagnosis performed on 1 June 2011. The data from 3 months before and 3 months after are considered as contemporary to the HCC diagnosis. Before this period is the history of the patient before the HCC diagnosis and after this period is the event occurred after the HCC diagnosis
