Figure 4. Exposed not sensitized children at birth show reduced mean hemoglobin levels throughout 36 months of follow-up.

The overall mean hemoglobin levels in exposed not sensitized (putatively tolerant) children were significantly lower than the exposed sensitized (p = 0.03) and not exposed children (p = 0.01) based on a repeated measures model (described in Table 2). Analysis was adjusted for children's height and weight (BMI) and helminth coinfection.
