This table shows the proportion of blood cultured cases in the validation set in which likelihood ratios of 5 and 10 for bacteraemia are predicted by the two models derived here, and by neutrophil count, lymphocyte count, and CRP protein when used as single variables. | ||||||

CRP, C reactive protein; LR, likelihood ratio. | ||||||

Modelled probability, CRP included | 0.197 | 0.304 | 168 | 8.2% | 57 | 2.8% |

Modelled probability, CRP excluded | 0.181 | 0.250 | 156 | 7.6% | 53 | 2.6% |

Neutrophil count (×10^{9}/l) | 20.7 | 26.2 | 92 | 4.5% | 39 | 1.9% |

Lymphocyte count (×10^{9}/l) | 0.263 | 0.149 | 70 | 3.4% | 23 | 1.1% |

CRP (mg/l) | – | – | 0 | 0.0% | 0 | 0.0% |
