Stabilization of SARS-CoV-2 RNA copy numbers by collection and transport devices at room temperature. Data shown refer to two independent experimental series with either 6 or 3 replicates, with the exception of eSwabs, which were examined in 3 independent experimental series with 6 replicates each. Columns represent mean ± standard deviation (SD). Copy numbers were extrapolated to the total amount of copies per device. ns = P > 0.05; * = P 0.01–0.05; ** = P 0.001–0.01; *** = P 0.0001–0.001; **** = P ≤ 0.0001.
