The graph on the front page of the Dec. 16th issue referenced the RAND Corporation's published study, The Appropriateness of Manipulation and Mobilization of the Cervical Spine. The telephone number to obtain a copy of the study was wrong. The correct number is: (310) 451-7002; fax: (310) 451-6915; e-mail: order@rand.org
