The text and Table 1 of the article “Understanding the Guidelines for Treating HIV Disease” (January 15, 1998, p. 315) contained a recurring typographical error. In each case that the CD4+ count was given—for example, 500 per mm3 (500 × 106 per L)—the multiplication sign that should have been part of the SI unit was inadvertently printed as a numeral 3.
