Soil-transmitted helminth and Giardia duodenalis Cq value and unadjusted and adjusted relative difference in Cq value among infected individuals at 2 year follow-up by household flooring status at enrolment

Finished floor includes majority wood, concrete, or tile household floors; unfinished floors were made of soil or earth. Box plots show median (IQR), and whiskers show 1·5 times the IQR. Relative differences in Cq values were estimated as the ratio of the arithmetic mean Cq value at 2 year follow-up in children with improved household flooring at enrolment to those with unimproved household flooring at enrolment minus 1. Adjusted relative differences in Cq values control for potential confounders associated with the outcome. CIs were adjusted for clustering at the village level. Ancylostoma duodenale was only detected in one sample in each country, so it is excluded from this figure. Cq=cycle quantification.
