Results of a series of multiple logistic regressions, with backward elimination procedure of the variables that were not significantly associated with white matter lesions. The initial model (n=309, 155 without white matter lesions and 154 with white matter lesions) included the 16 variables that were associated with white matter lesions with P values <.20 in Tables 1 and 2.
