Fig. 1. Volume and diversity of the operative procedures performed in children 0 to 2 yr old. The larger pediatric hospital (Large peds ) and smaller pediatric hospital (Small peds ) differ from other hospitals in Iowa in that they are more comprehensive (i.e. , perform many different types of procedures). Other facilities in Iowa perform a high volume of operative procedures in young children. However, those facilities perform much fewer types of procedures, mostly routine pediatric otolaryngology procedures. For example, the facility performing the most procedures (Most ) does just seven different types of procedures. The values on the horizontal axis of the lower pane were jittered slightly so that overlapping points would be visible.
