* SCD determined with patient self-report of difficulty thinking and confusion; ** log(π/(1 – π)) = β₀ + β₁ × Agelt55 + β₂ × LDA + β₃ × moderate + β₄ × severe + β₅ × Agelt55 × LDA + β₆ × Agelt55 × moderate + β₇ × Agelt55 × severe, where π is the probability of SCD; Agelt55 is an indicator (0/1) of age < 55; and LDA, moderate, and severe are indicators (0/1) of CDAI levels (age > 55 and CDAI remission are reference groups)
