The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.

100% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is.
