Random-number-generating software, accessed through the Web-based REDCap randomization tool, with a 1:1 trial-group assignment ratio was used to sequentially assign children to the BioFire FilmArray gastrointestinal panel or standard testing. As the results of the testing were provided to the responsible physician as soon as they were available to permit an assessment of the impact of the intervention on clinical care, after allocation was performed blinding was not feasible.
