Bulbar onset | Female gender | Age at symptom onset | Riluzole | Log diagnostic delay | |
---|---|---|---|---|---|

Bulbar onset | 1.93 | 5.83 | 0.69 | −0.26 | |

Female gender | 1.4 to 2.8 | 2.49 | 0.73 | 0.05 | |

Age at symptom onset | 3.9 to 7.8 | 0.5 to 4.5 | −6.08 | −0.06 | |

Riluzole | 0.5 to 1.0 | 0.5 to 1.0 | −8.0 to −4.2 | −0.07 | |

Log diagnostic delay | −0.4 to −0.1 | −0.1 to 0.2 | −0.1 to 0.02 | −0.2 to 0.1 |

The figures in the upper triangle represent the strength of association between each pair of variables. Where both variables are binary (onset site, gender, riluzole), the OR is given; where one is continuous (age, delay) and one binary, the difference in means is given; where both are continuous, Pearson's r is given. In each case, the 95% CI is given in the corresponding cell in the lower triangle. Figures in

**bold**represent associations for which the CI does not include the null effect (unity for ORs, zero otherwise).
