Snippet: A potential limitation to this study is that the samples utilized here are clinical isolates taken through the 211 course of normal patient care, and are not from a standard case definition as is utilized in some other studies 212 [12] . To test the robustness of the findings, the analysis will be repeated using only cases and controls that 213 were given a diagnosis code for acute respiratory infection on the same day as specimen collection, as .....
Document: A potential limitation to this study is that the samples utilized here are clinical isolates taken through the 211 course of normal patient care, and are not from a standard case definition as is utilized in some other studies 212 [12] . To test the robustness of the findings, the analysis will be repeated using only cases and controls that 213 were given a diagnosis code for acute respiratory infection on the same day as specimen collection, as per the 214 SESE database or MACAR. Appendix 3 lists the ICD-9 and ICD-10 codes used to define an acute respiratory 215 infection.
