* Missing data resulting from extracting laboratory results from unstructured information captured in the EHRs.
** Data indicate single diagnostic labels (i.e., if diagnostic information for a given condition exists multiple times for a single patient, the comorbid condition was counted only once). In addition, a single patient could have been diagnosed with more than one of the analyzed medical conditions.
