Corrections and Clarifications
In Traci Watson's article "Task force: Level the playing field" (14 May, p. 888), a table reprinted from a report by the National Institutes of Health contained incorrect figures. The numbers in the column labeled "Difference" should have read from top to bottom as follows: $3,945, $9,121, +$10,511, $343, $3,631, $3,249, $1,664, $5,967, and 2,754.
