Table 1 Clinical and basic laboratory data characteristics of study population, bacterial infected (all) and uninfected group, and bacterial infected group by infection (BSI, GII and UTI)

From: Can clinical signs or symptoms combined with basic hematology data be used to predict the presence of bacterial infections in febrile children under - 5 years?

Characteristic Study population Positive and negative bacterial infection Positive bacterial infections
N = 1099 Positive bacterial infections Negative bacterial infections BSI GII UTI
