Table 7 Independent risk factors for baseline colonization by ESBL-producing Enterobacteriaceae, CR-AB and/or CR-PA and MRSA from the primary and secondary analyses

From: A prospective surveillance study for multidrug-resistant bacteria colonization in hospitalized patients at a Thai University Hospital

Variables Adjusted OR [95% CI; p-value]
