Fig 1. Chronologies of ART regimens, drug resistance mutations detected by bulk sequencing and AS-PCR, and change in viral loads in enrolled individuals.

The chronological tables of (i) drug resistance mutations, (ii) viral load and (iii) ART regimens are depicted for each individual (A-F). (i) Resistance mutations detected: Bulk sequencing and AS-PCR results are shown in solid bars and closed circles, respectively. Their colors are matched with corresponding antiretrovirals shown in the ART regimen part of the table. (ii) Viral load: The arrows in each graph indicate the point that minor-drug resistance mutations were detected. The numbers indicated the ID of samples (S2–S6 Tables). (iii) ART regimens: Solid circles indicate the starting point of each regimen and the arrows indicate the period of each regimen.
