Dear Statlist.

I am trying to do meta-analysis for correlation coefficient to assess relationship between interleukin-6 and cardiovascular risk
I have the following data
id country type of study journal name journal year IL6 concentration (mean) n p value r lower higher
a Poland cross sectional cytokine 2016 0.94 57 0.001 0.5 0.2753 0.6729
b Hong Kong Prospective cohort NDT 2009 5.20 231 0.002 0.204 0.0769 0.3245
c POLAND cross sectional international journal of artificial organs 2003 5.57 43 0.05 0.32 0.0217 0.566
R=correlation coefficient
lower = lower limit of confidence interval
higher=higher limit of confidence interval

I have used the follwoing syntax to assess association:
metan r lower higher.
It did show that IL-6 is associated with cardiovascular risk.

My question is : I need to prove exposure response relationship.
Can I use the means of IL-6 and correlation coeeficient to try to prove that with increased mean of IL-6 , the risk of cardiovascular risk increase?

How can I do that?

Looking forward to hear back from you
