Dear ,
My name is Hatem Ali
I am trying to do meta analysis of hazard ratio to assess effect of rise in IL6 on overall survival
I have the following data
As you see, I have sample size, p value, lower and higher confidence interval.
However, only 3 studies are reporting HR, 2 are reporting OR, one is reporting chi square.
Is there a way to calculate hazard ratio from the studies reporting odds ratio or chi square?
In other words,can I convert Odds ratio to hazard ratio? and can I convert chi square to hazard ratio?
If that is not possible, then , can I calculate Relative risk for each study from the data I have?
Can I calculate RR from HR, 95% CI , sample size and P value?
Can I calculate RR drom OR, 95%CI, sample size and P value?
Can I calculate RR from chi square, sample size and P value?
Finally , after calculating HR, the syntax to use is : metan HR lower higher, counts random
is that correct?
How can I add the name of the studies to the forest plot using this syntax?
Looking forward to hear back from you
