Am I using the right statistical tests?

If the mean ranks would have been the same in the sample, then p = 0.003 would not have been possible.

With kind regards

i didnt mean equal to each other, I meant if the mean ranks would have been the same as in my result, maybe that wasnt clear...
anyway - so as i understand - in my test population - these results mean that troponin does not affect the chance to die, right? if that's the case, just to understand this properly - which result would mean that a higher troponin value increases the chance to die (i.e. be in group 1)?
