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

C/O: Cut-off value applied for s-QBC in CFU/ml. * Values in columns represent p values. # Correct classification of cases as acute GBS UTI or ABU infection category as determined by the testing model.
