Table 4. Association of GST genotypes with CD4+ count above 350 cells/mm3.
| Genotypes | CD4+ count (cells/mm3) | Odds Ratio | 95% CI | p-value | ||
|---|---|---|---|---|---|---|
| >350 | 200–349 | <200 | ||||
| GSTM1 null | 27 | 6 | 9 | 1.10 | 0.54–2.25 | 0.475 |
| GSTT1 null | 22 | 9 | 5 | 0.92 | 0.44–1.95 | 0.488 |
| GSTM1+GSTT1 | 55 | 15 | 23 | 0.74 | 0.40–1.35 | 0.199 |
| Both null | 10 | 1 | 0 | 6.44 | 0.81–51.49 | 0.039* |
*Statistically significant p-value.
The odds ratio, confidence intervals and p-values were obtained by a one-tail test analysis using the online tool from http://vassarstats.net/odds2x2.html. The comparison was done between patients with CD4+ counts >350 cells/mm3 and <350 cells/mm3.
