Figure 4.

Relationship between the proportion of zero egg counts and the mean weight of female Ascaris lumbricoides. Top row: a scatter plot of the proportion of zero egg counts per stratum of female Ascaris mean weight in the baseline (A), 1^st (B) and 2^nd (C) re-infection populations. Bottom row: logit of the proportion of zero egg counts per stratum of the natural logarithm of female mean weight baseline (D), 1^st (E) and 2^nd (F) re-infection populations showing approximately linear relationships.
