Table 1.

Marginal odds ratios for various values of the conditional odds ratio, the conditional intercept (β0C) and corresponding mean response when X=0 (π0C), and the standard deviation (SD) of the normally distributed radiologist-specific effects.

Marginal odds ratio, exp(β1M)
Conditional odds ratio, exp(β1C) SD for X=1 SD for X=0 β0C = −2.2 (π0C = .10) β0C = −1.1 (π0C = .25) β0C = 0 (π0C = .50) β0C = 1.1 (π0C = .75) β0C = 2.2 (π0C = .90)
