Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:The study has several limitations. First, asymptomatic people were not enrolled as index cases, affecting our ability to fully characterize all types of transmission chain. Second, we did not find any evidence of decreased risk of transmission in individuals who reported mask use. While this finding collides with the evidence reported elsewhere,8 we did not have fine-grained data on type of mask (surgical vs FFP2), use of other measures of PPE or other infection control practices, thus limiting our ability to make clear inferences about the impact of PPE on transmission risk. Mask usage is likely correlated with type of exposure which might further confound associations but we did not note any association between mask use and risk either in our unadjusted analysis (Table 3) or in a multivariable model excluding type of exposure (data not shown). Third, we used time to symptom onset (with later confirmation of infection) rather than time to positive PCR test based on serial testing. Nonetheless, accurate calculation of the incubation period was feasible because of the prospective nature of the study, accurate identification of exposure by face-to-face interview, and intensive active and passive monitoring of exposed contacts. We followed participants over 14-day periods, thus incubation periods beyond 14 days may not have been detected. Within each cluster we cannot be completely certain about the directionality of transmission, but our inclusion criteria including the absence...
