Hello, everyone
Today I read this research paper "Plozasiran (ARO-APOC3) for Severe Hypertriglyceridemia
The SHASTA-2 Randomized Clinical Trial" (doi:10.1001/jamacardio.2024.0959).
I am very interested in the line of Figure 2. According to my understanding, the model used in this research probably is a linear mixed model, and follow-up time is an independent factor. What I am not sure is how the author estimated the confidence interval of the outcomes in Figure 2? Using the linear mixed model? Or other methods?
Please let me know your ideas. Thank you.
