Unstandardised regression coefficient | Confidence interval | p value | |
---|---|---|---|

Regression coefficient is the change in the dependent variable (log PD_{20} or bronchodilator reversibility) per unit change in the independent variable (FEV_{1} % predicted, log eosinophil count). | |||

Log PD_{20}, R^{2}=0.45 | |||

FEV_{1} % predicted | 0.02 | 0.01 to 0.03 | 0.001 |

Log eosinophil count | –0.013 | –0.32 to 0.29 | 0.93 |

Inhaled steroids (yes v no) | –0.42 | –0.89 to 0.06 | 0.083 |

Constant | 1.47 | 0.45 to 2.48 | 0.006 |

Bronchodilator reversibility, R^{2}=0.25 | |||
