Hello there, I would like to correlate the mRNA expression of a gene obtained from patient blood samples with surrogate parameters like HbA1c and data like body weight, age, etc. However, I am unsure and confused about the correct way to do it. I did not find a solution on the web so far.
Which qPCR-data should you I use (dCT, ddCT, 2^-ddCT)?
If it favorable to use log-transformed data, or does it distort the results?
Is it statistically correct to simply use an xy-graph and do a correlation analysis?
Regards!
