The distribution of the different direct-acting antiviral (DAA) regimens per geno—and subtype that individuals failed on. All regimens are with or without ribavirin. In the upper graph the most common genotypes are outlined. Abbreviations: N.D = non-determinant, 1genPI = first generation protease inhibitors as boceprevir and telaprevir, ASV = asunaprevir, DAC = daclatasvir, DAS = dasabuvir, ELB = elbasvir, GZR = grazoprevir, LDV = ledipasvir, OBV = ombitasvir, PTV/r = paritaprevir boosted with ritonavir, SIM = simeprevir, SOF = sofosbuvir, VEL = velpatasvir, VOX = voxilaprevir.
