Box plots of pol replication capacities (RC), by amino acid polymorphisms and subtype. Results for the 3 amino acid positions (protease polymorphisms I62V and I64V and reverse transcriptase polymorphisms A272P) with significant interresidue differences in median pol RC are shown. The bars represent the highest and lowest pol RC of each category. P values for the first-stage comparison are Bonferroni corrected.
