The full title was <i>Recalibrating SARS-CoV-2 Antigen Rapid Lateral Flow Test Relative Sensitivity from Validation Studies to Absolute Sensitivity for Indicating Individuals Shedding Transmissible Virus</i> which was not descriptive in terms of the main finding, and too long for HN.<p>The paper's main argument is the PCRs are very sensitive to individuals with Covid-19 RNA shedding in their upper respiratory tract, but that this often doesn't indicate infectiousness. Adjusting for this fact, they show that LFTs may offer a sensitivity of above 80 % for <i>transmissible</i> individuals.
