Effects of geohelminths on outcomes stratified by SPT
SPT reactivity was strongly associated with wheeze (adj. 4.13, 95% CI
2.80-6.08, P<0.001) and asthma (adj. OR 2.32, 95% CI
1.57-3.42, P<0.001). We explored if effects of geohelminths on
outcomes might vary by SPT (Figure 2 and Table 4). Although interactions
were seen for SPT on geohelminth-outcome associations, they were not
highly significant. However, overall associations between maternal
geohelminths and wheeze/asthma were positive among atopic but negative
among non-atopic children.
