My null hypothesis: TXA does not reduce the progression of intracranial haemorrhage in isolated traumatic brain injury when given less than 3 hours post injury.

What level of data measurement will i use to collect data on the increase in haemorrhage size greater than 25% on CT scan (primary outcome) and measuring disability and blood product use as secondary outcomes?

And how will i analyse the data? what statistical test? i was thinking the Mann-Whitney U test??????

Thank
Kate : )

Thu, 20 Oct 2016 14:03:34 GMTIn case of 2 population, the first has HR X for the study's outcome (between the exposed and non-exposed groups), and the second has HR of Y (between the exposed and non-exposed groups), which tests should be done in order to compare between these HR's?
