Table 1.
Distribution of HIV-1 pol Sequences According to Subtype and Cohort.
| HIV Subtype | Database sequences (FCs) | FCs | GP | Total | P-values‡ (Proportions in FCs vs GP) |
|---|---|---|---|---|---|
| Subtype A1 | 15 (34.1%) | 100 (47.4%) | 177 (50.4%) | 292 | 0.24 |
| Subtype D | 14 (31.8%) | 70 (33.2%) | 122 (34.8%) | 206 | 0.35 |
| Subtype C | 1 (2.3%) | 2 (0.9%) | 9 (2.6%) | 12 | 0.08 |
| Inter-subtype recombinants | 14 (31.8%) | 39 (18.5%) | 43 (12.2%) | 96 | 0.02* |
| Total | 44 | 211 | 351 | 606 |
‡P-values according to the two-sample test of proportions.
*Significant difference in inter-subtype recombinants proportion; although the lower limit of the confidence interval (CI) is very close to zero, 95% CI (0.0004–0.126).
