- This web-based tool has been developed based on the publication from Beksac et al in order to calculate the probability of intensive care unit (ICU) admission or asymptomatic
presentation. To be able to calculate the risk; age, blood type, number of comorbidities and Killer-immunoglobulin-like Receptor (KIR) genotypes are required. KIR haplotypes
are described in Figure 1.
Description of the Model:
* Prediction Model Formula: exp(-3.52 + 1.56 Age Group - 2.74 Blood group (type-A vs others) + 1.26 number of comorbidities - 2.46 tAB1 with ligand + 3.17 tAA with ligand)
* Correct Classification Rate for Asymptomatic (specificity): 92.9%
* Correct Classification Rate for Critical Care (sensitivity): 76%
