The “+” and “-” symbols indicate whether a given risk parameter was included or excluded in the corresponding model. lnlik is the maximized ln likelihood for each model.

^a P value for the comparison of each model versus the null model with no effects.

^b P value for the comparison of each model versus the child genotype model including R1 and R2.

^c P value for the comparison with the full model including all risk parameters (R1, R2, S1, S2, and Im).
