We compute the expected and observed numbers of cases for each cylinder and perform amaximum likelihoodtest with null hypothesis H 0 :“There is no difference in risk of COVID-19 between the inside and outside of the cylinder”, andalternative hypothesis ...
We excluded individuals with one or more positive tests in the period 31 to 180 days after the first positive test. In this way, we could exclude new onset symptoms that were due to a new SARS-CoV-2 infection and not related to the first SARS-CoV-2 infection (i.e., all positive tes...
For rs657152, the overall frequency of protective allele C was 0.5468 (222/406), with the lowest rate found in the critical group (allele frequency (AF) = 0.382, 13/34, Fisher’s exact test P = 0.04896). For rs11385942, the risk allele GA was not detected in any patient ...
Differences between the distributions evaluated using 2-tailed Mann-Whitney U test. Differences between categorical variables, evaluated using 2-tailed Fisher exact test with ORs calculated using the Baptista-Pike method. Common variable immunodeficiency (CVID) was the most common PID in this cohort (...
and contacts of confirmed cases traced over the previous two weeks [130]. In individuals with a high suspicion rate, the test was repeated after 48 h [130]. The airport testing included body temperature and clinical assessment and the use of a rapid diagnostic test for severe-acute-respiratory...

In order to screen Ab candidates for neutralizing capability in vitro, most groups test Abs against authentic living SARS-CoV-2, while some use pseudovirus with reporter readouts. A few methods have been used to quantify inhibitory concentrations, such as plaque reduction neutralization test (PRNT...
For mild COVID-19 (a) and severe COVID-19 (b), graphs show the general disease course timeline and the magnitude of innate (blue) and adaptive (orange) immune responses over time. Dashed lines represent the time course for response in patients with pre-existing adaptive immunity. For sever...
The MDL change statistics has been proposed as a test statistics in the hypothesis testing for change detection14,18. It is defined as the difference between the total codelength required for encoding data for the non-change case and that for the change case at a specific time pointt. A nu...
