Effects of geohelminths on secondary outcomes
There were no significant associations of geohelminths with airways reactivity, FeNO and nasal eosinophilia (Figure 2 and supplementary Table 3). When considering parasite species and burden, elevated FeNO was associated with moderate/heavy parasite burdens with A. lumbricoides both in mothers (vs. uninfected, adj. OR 2.19, 1.23-3.90, P=0.008) and children at 5 years (vs. uninfected, adj. OR 2.27, 1,10-4.70, P=0.027). After co-adjusting for maternal and child infection intensities, only the maternal effect remained significant (vs. uninfected, adj. OR 2.20, 95% CI 1.16-4.19, P=0.016).
