Faecal egg count reduction rates for A. lumbricoides, T. trichiura and hookworms.

1FEC, faecal egg count, (egg per gram of stool).2CI, confidence interval. The confidence intervals of the egg reduction rate were calculated using a bootstrap resampling method [45].3ERR, egg reduction rate. The ERR estimates were obtained by dividing the difference between the arithmetic mean of the pre- and post-treatment FEC (at group level, ignoring individual variability) by the mean of the pre-treatment mean count (see text).4NA = Not applicable.5HW = Hookworm.
