Mean weight and height of children according to <i>Giardia</i> infection over time.

<p>All values are mean (SEM). ^* Significant difference (lower) compared to non infected group (Independent t-test, <i>P</i><0.05). <b>^†</b> Significant difference (higher) compared to previous assessment (Paired t-test, <i>P</i><0.05). Trend lines represent the linear weight and height increments (repeated measures ANOVA).</p
