I have a question regarding the interpretation and comparability of the hazard ratios in a competing risk model obtained from the stcrreg command (Fine and Gray’s Model). I have two competing exit reasons: Exit 1 and Exit 2. When I obtain hazard ratios for my covariates from Exit =1 it looks like the following:

Code:

stcrreg Covariate 1 Covariate 2 Covariate 3, compete(failcode = 2 )

Cause | |

EXIT 1 | |

Covariate 1 | 1.211 |

[1.32] | |

Covariate 2 | 0.0560* |

[-1.70] | |

Covariate 3 | 0.2*** |

[2.70] |

When I obtain hazard ratios for my covariates from Exit =2 it looks this:

Code:

stcrreg Covariate 1 Covariate 2 Covariate 3, compete(failcode = 1 )

Cause | |

Exit 2 | |

Covariate 1 | 1.434** |

[2.31] | |

Covariate 2 | 0.0409* |

[-1.85] | |

Covariate 3 | 0.4*** |

[2.31] |

I interpret this as: “Covariate 3 lowers my probability of exit cause 1 by 60 %”

My question: Can I compare the results from Model 1 and Model 2 in regard to covariate 3?

Is it right to interpret the difference (of 20 %) for covariate 3 between Exit 1 and Exit 2? So to say that “For individual with a higher covariate 3 the probability is 20 % lower experiencing exit 2 then exit 1?

Thanks a lot and regards,

John
