  • a SG was dichotomized by using a cutoff of 1.015.

  • b Missed indicates that the patient had a UTI but was not treated with antibiotics.

  • c Dipstick consisted of LE and nitrite tests using the cutoffs provided above for each of the components.

  • d Urinalysis includes the dipstick, WBC/hpf, and bacteria per hpf using the cutoffs provided above for each of the components.
