The effect is actually equivalent for men and women who passed away ahead of and you will as well as ages 65 (Time = 0.78 and you may Time = 0.75, respectively), and everyone whom passed away once they was indeed over the age of 65 (Hr = 0.81 and you can 0.78, respectively). Even though they were short inside the magnitude IOS dating review, these people were all of the notably additional (all of the ps Fig. step three ).

I went the brand new baseline model once again, with young people MHT get and you can years given that predictors, and all of-end up in mortality since a result. So it failed to change the results (Hour = 0.80, 95% CI = 0.79, 0.81).
