*Loglikelihood from a single attribute divided by the sum of partial loglikelihoods of all factors.
†p Value based on the loglikelihood test. ∞Factor risk score outcome is partially confounded by factor age, and therefore its impact cannot be interpreted.
‡Explained deviance due to the allocation of cardiologists to blocks in the experimental design.
CAD, coronary artery disease; NA, not applicable.
