“All cases” are presented as numbers (%). Time to positivity (TTP) is presented as median hours with interquartile range (IQR). 1Absolute neutrophil count < 0.5 × 109/L at the time positive blood culture was drawn. 2Including osteomyelitis, spondylodiscitis, gastroinstestinal infection, urogenital infection, airway infection, and soft tissue infection. 3Univariate statistical analyses were performed using the Mann-WhitneyU test or the Kruskal-Wallis test. 4Statistical analysis performed via multivariate regression analysis. 5S. mitis indicated as baseline NBHS group in statistical analysis
