   The endline survey was an online survey on REDCap and included questions about student’s previous positive testing history (if the student has ever been tested positive for COVID-19).	REDCap suggested: (REDCap, RRID:SCR_003445)

   Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:

   The primary limitation of the current study is that we could not contact the nominated friends to collect data about their actual COVID-19 testing history because this was an opportunistic study that leveraged a larger RCT. Participants might had imperfect and out of date information about their friends’ COVID-19 status. This particularly could have caused underestimation of the true COVID-19 prevalence among the nominated friends. Moreover, because students were participating in a study about COVID-19, it might have primed them to recall their friends who had been tested positive in the past. This selection bias might have caused an overestimation of the true prevalence of COVID-19 positivity among nominated friends. Despite these limitations, our study bolsters the strength of the acquaintance sampling method in detecting those who are more likely to contract the disease early. These findings could be useful for university policy makers when developing mitigation testing programs and intervention strategies against COVID-19 spread. We suggest future studies assess the feasibility of this sampling method in mitigation/surveillance testing and immunization strategies at university level.
