Listed are p-value for bootstrap comparison of linear-regression fits of Ct values of nasal swab vs. NP swab for observed samples for arms 1-6 from Table 1 vs. 10,000 random samples of either Procedure 1 (top three rows), Procedure 2 (next three rows), total (next six rows). Bottom two rows are bootstrap comparisons of all Procedure 1 (i.e., arms 1-3) to total and Procedure 2 (arms 4-6) to total. All comparisons show p>0.05, interpreted as no significant differences among arms and procedures.
