Figure 1
Total and free elvitegravir (EVG) and cobicistat (cobi) plasma concentrations in a patient during pregnancy and postpartum (closed circles: EVG; open triangles: cobi; continuous lines: total concentrations; dashed lines: free concentrations). The threshold lines represent the EVG concentration inhibiting viral suppression by 95% (IC95 = 45 ng ml–1) and the EVG concentration producing a 90% effective response (EC90 = 0.53 ng ml–1)
