In the article “Common Adverse Effects of Antiretroviral Therapy for HIV Disease” (June 15, 2011, page 1443), there were several errors in Figure 1 (page 1445). In multiple locations, the word “or” was inserted between two drug names instead of a plus sign (+), which incorrectly implied that either of the two drugs listed should be administered, rather than both drugs needing to be administered. The online version of this figure has been corrected, and the corrected Figure 1 is reprinted below.
