Multivariate Cox regression analysis results: overall survival, n = 50, deaths = 14 | ||||
---|---|---|---|---|

Variable | Hazard ratio | Lower 0.95 confidence limit | Upper 0.95 confidence limit | P |

Node stage | 2.09 | 0.98 | 4.44 | 0.06 |

FDG | 1.64 | 0.95 | 2.83 | 0.08 |

Tumor stage | 1.26 | 0.66 | 2.42 | 0.48 |

Age | 1.52 | 0.80 | 2.91 | 0.20 |

T/B | 1.97 | 0.99 | 3.93 | 0.06 |

NOTE: Median follow-up for this data set was 61 weeks. For the continuous variables, the hazard ratio and the confidence intervals should be interpreted as the increase in survival risk associated with an increase of 1 SD of the covariate (refer to Table 2 for SD values).
