Δ WAZ (3–6 mo)	0.20(0.12,0.28)	0.16(0.11,0.22)	0.29(0.20,0.37)*	0.15(0.10,0.19)

All values are mean (95% confidence interval); Δ: change; mo: months; WAZ: weight-for-age Z-scores; HAZ: height-for-age Z-scores; WHZ: weight-for- height Z-scores.

^*Significant difference compared to Giardia-negative children (P<0.05; Independent samples t-test).
