I have a study where subjects have received treatment to one eye, the other eye is untreated and is acting as a control. There are 3 measures (of retinal thickness) taken in each eye.
The model I am using is:
fit <- lmer(Thickness~tx + Region + (1|ID) + (1|ID:Eye), data)
tx is treated / untreated and
Region is the repeated measure.
I need a sentence to describe this for publication!
My current attempt looks like this:
Changes of retinal thickness between treated and untreated eyes was examined using a linear mixed effects model. Each subject was considered to have an independent intercept and the three regions within each eye were treated as repeated measures.
Is this correct, could it be better?
