ANDC is an acronym for age, NLR, D-dimer and CRP
Patient selection: adult with COVID-19
Outcome: mortality
Parameters:
(1) age in years from 20 to 90 years
(2) neutrophil to lymphocyte ratio (NLR), from 0 to 40
(3) plasma D-dimer in mg/L, from 0 to 20
(4) serum CRP in mg/L, from 0 to 260
points for age =
= (1.141428 * (age)) - 22.82857
points for NLR =
= 1.615 * (NLR)
points for D-dimer =
= 5 * (D-dimer)
points for CRP =
= 0.13923 * (CRP)
total score =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: 0
• maximum score: 280.7
value of X =
= (0.07059 * (score)) - 7.195
probability of mortality =
= 1 / (1 + EXP((-1) * X))
