Hi all in Statalist,
I need help with having two reference lines in the same plot.
In our study, we analyzed blood samples (with Sampletype (=Sample) in duplicates (Run 1 and 2) in a reference analyzer (X) and a test analyzer (Y). T3, MoK, LyS etc. are analytes measured in the blood samples by the analyzers. We need to show that the results lie within reference limits. I hereby attach an example of my data:
I plot the T3_X analyte according to the following:
The "yline" above is for the Id=X. The reference limits for Id=Y are 1.96 & 2.2 "ylabel(1.96 2.2). I wonder how to have the limits for both Id X & Y in the same plot? (For help: suggest that we run Id X from Day 1 to 20 and changed to Id Y from Day 21 to 30)
