Table 1.
Characterization of the study groups according to copro-parasitological results in relation to S. mansoni infection: Group <4 epg (n = 42), Group 4 to 99 epg (n = 60), Group ≥100 epg (n = 11), and Negatives (n = 26). Indicated for each group are sex distribution, median age, parasite load, and presence of co-infections.
