Table 2 Comparisons of demographic and clinical data between the deceased and survived groups of the 42 patients with CRB; Variables with a p -value < 0.1 by univariate analysis were subjected to multivariate analysis

From: Discrepancy between effects of carbapenems and flomoxef in treating nosocomial hemodialysis access-related bacteremia secondary to extended spectrum beta-lactamase producing klebsiella pneumoniaein patients on maintenance hemodialysis
