For example, the treatment group experienced full symptom resolution in a median of 5 days sooner than the control group. Or survival increased by a median of 90 days. These measures help the reader understand the practical importance of hazard ratio results. There is no direct calculation from ...

Hazard ratio calculation for threshold regression model
hazard ratio for cancer of the lung in very heavy drinkers is also about 6 but this association does not hold up when adjusted for smoking. v) A truly extreme example may also be helpful. Cancer of the breast is the commonest serious cancer in women. But men can also develop breast ...
Some researchers suggest assessing the prognostic value according to the hazard ratio (HR) of each N classification. 3 In light of these considerations, data collected from 1,247 patients with gastric cancer who underwent radical surgery between January 2005 and December 2009 at First Affiliated ...

The calculation options dialog box sets a value (default is 10000) for "SPLITTING RATIO"; this is the ratio in proportionality constant at a time t above which StatsDirect will split your data into more strata and calculate an extended likelihood solution, see Bryson and Johnson, (1981)....
Now when you include the interaction term there is a lot more complicated calculation going on to get the hazard ratio that depends on the reference values for both variables. Your "Surgery Type1 vs Type2 At " will always tell you what your variable's current reference value is, but then...
