We’re writing a pilot program that we did at 7 hospitals over about 2 years. We have data on two items, by site and month:
(1) referral rate (% of patients referred to the program)
(2) participation rate (% of patients who chose to participate)

It’s a mess because there’s a lot of variability – and that might be the story – but how to show it? Needs to be grey scale for a journal. Yikes!

Excel data are here.
