Determination of infection by microscopy using Kato-Katz (KK) for S. mansoni and 10 mL filtration (F) for S. haematobium compared against PCR detection for both species. The agreement statistics determined by Kappa co-efficient has been provided (CI = Confidence interval).
| Schistosome species | KK⁎ +/PCR + | KK −/PCR − | KK +/PCR − | KK −/PCR + | Kappa coefficient (95% CI) |
|---|---|---|---|---|---|
| Schistosoma mansoni | 45 (49.4%) | 38 (41.8%) | 0 | 8 (8.8%) | 0.824 (0.71 – 0.94) |
| Schistosome species | F$ +/PCR + | F −/PCR − | F +/PCR − | F −/PCR + | Kappa coefficient (95% CI) |
|---|---|---|---|---|---|
| Schistosoma haematobium | 21 (12.9%) | 84 (51.5%) | 0 | 58 (35.6%) | 0.271 (0.17 ‐ 0.37) |
KK⁎ data is available for only 91 samples.
F$ data is available for 163 samples.
