Where this hospital sits among its peers
A position, not a grade. Each line names the figure, how it is measured, and the hospitals it is placed among: short-term acute care hospitals in the same state and the same bed-size band, each on its latest filed year. Under it, the same figure across every hospital that filed for the year — a larger set, and a different one.
