Table 2 Prognostic values of age and semi-quantitative bacteruria count (s-QBC) for differentiating cases of acute GBS UTI and ABU

From: Prognostic value of semi-quantitative bacteruria counts in the diagnosis of group B streptococcus urinary tract infection: a 4-year retrospective study in adult patients

Testing Model s-QBC* Age* Constant % Correct#
Univariate (s-QBC)     
Continuous s-QBC 1.13x10-5 NA -1.776 74.3%
C/O: 103, 104 or 105 0.92-1.10 NA -1.13-2.02 74.3%
Univariate (Age)     
Continuous Age NA 0.025 -2.24 74.7%
Continuous s-QBC 1.04x10-5 0.021 -2.59 74.7%
C/O: 103, 104 or 105 0.76-0.87 0.022-4 -2.32-2.97 74.7%
