Fig. 1From: Variability of efavirenz plasma concentrations among pediatric HIV patients treated with efavirenz based combination antiretroviral therapy in Dar es Salaam, TanzaniaBox plots showing association between efavirenz plasma concentrations and the virological, immunological and clinical outcomes. Key: These graphs show efavirenz mid-dosing concentrations in children; central line represents median values while box and whiskers represent interquartile range and 10th –90th percentile, respectively, and individual points are outliers. Dotted lines represent 1 μg/mL and 4 μg/mL (Therapeutic range). a Efavirenz concentrations vs Viral load categories (< 400 copies/mL, 400–1000 copies/mL and > 1000 copies/mL). b Efavirenz concentrations vs CD4 categories (< 200 cells/μL, 200–499 cells/μL, > 500 cells/μL). c Efavirenz concentrations vs Nutritional status (MUAC). d Efavirenz concentrations vs weight bands in Kg and efavirenz doses in mgBack to article page
