These proportions were statistically equivalent within 1%, using two 1-sided test with a P value of .04. There were 341 febrile infants (345 episodes) with positive urinalysis treated with antibiotics without lumbar puncture. Zero cases of missed bacterial meningitis were identified (95% CI: 0%\u20131.1%).
