Patient selection: adult with COVID-19, on admission to the hospital
Parameters:
(1) age from 20 to 100 years
(2) percent lymphocytes from 0 to 90 percent
(3) serum C-reactive protein in mg/dL, from 0 to 22
(4) serum LDH in U/L, from 50 to 650
(5) serum CK in U/L, from 0 to 4,000
(6) serum BUN in mg/dL, from 0 to 240
(7) serum calcium in mg/dL from 2 to 12
points for age =
= (0.39875 * (age)) - 7.975
points for calcium =
= (-1.76 * (calcium)) + 21.12
points for CK =
= (0.025 * (CK))
points for CRP =
= (1.47727 * (CRP))
points for LDH =
= (0.02483 * (LDH)) - 1.241667
points for lymphocytes =
= (-0.5333 * (lymphocytes)) + 48
points for BUN =
= (0.16875 * (BUN))
score =
= SUM(points for all 7 parameters)
X =
= (0.089785 * (score)) - 7.9443
probability of severe disease =
= 1 / (1 + EXP((-1) * X))
