Table 4. The effect of mixed Schistosoma infection on Ct-values in S. mansoni egg-positive and Schistosoma PCR-positive subjects. a .
| Egg-based S. mansoni infection intensity | Single S. mansoni | Mixed Schistosoma infection | p-value | ||
|---|---|---|---|---|---|
| n | Median Ct-value (IQR) b | n | Median Ct-value (IQR) b | ||
| Light intensity (1–99 epg) | 20 | 25.2 (22.8–28.1) | 18 | 22.7 (22.0–26.6) | 0.126 |
| Moderate intensity (100–399 epg) | 10 | 21.3 (20.7–22.1) | 27 | 21.0 (20.3–22.9) | 0.674 |
| Heavy intensity (≥400 epg) | 9 | 20.6 (19.4–22.2) | 37 | 20.0 (18.9–21.0) | 0.397 |
| Total | 39 | 22.5 (21.1–25.2) | 82 | 20.9 (19.8–22.9) | 0.003 |
a Based on microscopy on 2 stool samples and ≥10ml of urine.
b Median and IQR (interquartile range, calculated using Tukey’s hinges) are given for egg-positive and/or PCR-positive individuals only.
