Results of microscopy with the numbers of S. haematobium eggs/10 mL urine divided into egg counts of 1–49 and > 50 eggs/10 mL indicative of low and high intensity of infections respectively and real-time PCR results divided into high (Ct < 30), moderate (30 ≤ Ct ≥ 35), and low (Ct > 35) DNA loads and negative (no amplification detected in 50 cycles)*
