I have data as follows:
Exposure: blood glucose levels (%) I have grouped into 4 levels: Group 1 - Less or equal to 6% (very good control) Group 2 - 6.1 - 8% Group 3 - 8.1 - 10% Group 4 - more than 10% (very bad control)
Outcome (mean difference and SD): Amount of bone loss in millimeters
I have been advised to perform Categorical DRMA based on robust error meta-regression. But I am unable to find any example on continuous outcomes.
Please kindly recommend any example/STATA manual that I can read. I am a beginner in STATA and deeply appreciate advice.
Thank you in advance!
