### Data description Results from this study can be replicated using the scripts in the Analysis component and the dataset posted on this page. ### Parent trial This study was nested within the WASH Benefits Bangladesh trial. For additional information about the study design and associated datasets, visit the trial's OSF page: [https://osf.io/wvyn4/](https://osf.io/wvyn4/). ### Variables In this dataset, variables use the following shorthand: - `ac`: *Ancylostoma ceylanicum* - `ad`: *Ancylostoma duodenale* - `al`: *Ascaris lumbricoides* - `hw`: hookworm - `na`: *Necator americanus* - `tt`: *Trichuris trichiura* - `ss`: *Strongyloides stercoralis* - `IAC`: internal amplication control in qPCR #### identification and demographic variables - `clusterid`: id for study cluster - `dataid`: - `block`: randomization block - `personid`: identification of type of child enrolled (C1: 18-27 month old child; O1 5-12 year old child; T1: target child; T2 target child twin) - `sex`: child sex - `dw`: indicator for whether child was dewormed in the prior 6 months (caregiver reported) - `aged`: age in days - `agem`: age in months - `agey`: age in years #### Kato-Katz variables - Variables ending in `epg` are eggs per gram counts from Kato-Katz - Variables starting in `log` and ending in `epg` are the natural log of eggs per gram. If the original eggs per gram count was 0, the natural log of 1 was imputed. - Variables ending in `kk` are indicators for whether at least one soil-transmitted helminth ova was detected in during Kato-katz - `sth` is an indicator for whether any soil-transmitted helminths were detected using Kato-Katz - Variables ending in `int` are categorical variables indicating infection intensity levels using WHO cutoffs - Variables ending in `mh` are indicators for whether the child had a moderate-to-heavy intensity infection using Kato-Katz. - Variables ending in `mh.f` are labeled with strings for whether the child had a moderate-to-heavy intensity infection using Kato-Katz. #### qPCR variables - Variables starting with `CTmean` are the mean of cycle threshold values taken across replicate runs for each stool sample. - Variables starting with `CTSD` are the standard deviation of cycle threshold values taken across replicate runs for each stool sample. - Variables starting with `positive.` are indicator variables indicating whether the mean cycle threshold value was <40 for a sample (i.e., an indicator for whether the test was positive using qPCR). #### Other variables - Variables with the prefix `gold` are indicators that pool results from Kato-Katz and qPCR. The variable equals 1 if either test was positive.
