Dear Martin!
As I told you last Wednesday at the ‘debriefing’ I would need a month of spare time to retrieve them (~100,000 data pairs in various formats). I can only serve with an overview. 133 cross-over studies, 2843 subjects, AUCt or AUCτ:

R² of my sample has an interesting distribution…
Of course, correlation depends on the sample size* – but you get an impression.
Studies with low correlations contained one ‘outlier’ each but were still large enough to show BE (well, that was my selection bias).

❝ This is extremely interesting. I would by happy if you can you provide some summary regarding the correlation between time points. (e.g. was the correlation constant over time, …).
