*Adverse events were obtained from medical charts and graded by using the National Institutes of Health classification for side effects (http://www.niaid.nih.gov/LabsAndResources/resources/DAIDSClinRsrch/Documents/daidsaegradingtable.pdf). ALT, alanine transaminase; CNS, central nervous system.
†Mild pruritus and rash.
‡Telogen effluvium.
§Regressive retinopathy.
¶Grading was done during the follow-up by using available nadir of hemoglobin. For HIV-negative patients, the severity of anemia was graded as follows: grade 1, 10.0–10.9 g/dL; grade 2, 9.0–9.9 g/dL; grade 3, 7.0–8.9 g/dL, grade 4, <7.0 g/dL. For HIV-positive patients, the severity of anemia was graded as follows: grade 1, 8.5–10.0 g/dL; grade 2.0, 7.5–8.4 g/dL; grade 3, 6.5–7.4 g/dL; grade 4, <6.5 g/dL.
