Drug resistance mutations present in study participants.

The table shows SDRMs in column 2, marked with an asterisk (*), and frequency of DRMs (columns 3 and 4), entropy score (column 5), and selection pressure (column 6) for each drug resistance mutations sites in both ART-naïve and ART-experienced groups. In column 5, the grey shaded column indicates high entropy sites, the entropy score which was greater than the mean value characterized as high, and the entropy score less than the mean value characterized as low entropy in ART-naïve (mean = 0.28) and ART-experienced (mean = 0.4) group, while ‘0’ represents no entropy. In column 6,—values and + values indicate the probability of negative and positive selection pressure on DRM sites, respectively, whereas, the bold and underlined values show high selection pressure between ART-naïve and ART-experienced groups.
