Odds ratios (OR) from the logistic regression model with 95% confidence intervals
(CI) used for the prediction of the probability of nasal carriage of Methicillin-resistant
Staphylococcus aureus |

Variable |
Crude OR (95% CI) |
Adjusted OR (95% CI) |
p_{W} |
Score |

Age | 1.04 (1.02,1.05) | 1.03 (1.01,1.05) | < 0.001 | Age - 10 |

Nursing home | 5.94 (3.02,11.67) | 3.00 (1.45,6.19) | 0.003 | 37 |

Admission diagnosis: A or J | 4.84 (2.24,10.45) | 3.18 (1.39,7.28) | 0.006 | 39 |

Emergency admission | 2.58 (1.48,4.5) | 1.93 (1.08,3.47) | 0.028 | 22 |

P_{w}: p-value according to the Wald-Test. An initial score for a patient is calculated
by subtracting 10 from age and adding values in column “Score”, if the corresponding
variable is true. If prevalence differs from 2.3%, a correction score (Figure
5) has to be added.
