A series of separate multivariate logistic regression models (one for each income source as a dependent variable) including sex and age as independent covariates also found positive urine cocaine tests to be significantly associated with any 30-day illegal income (β = 0.78, SE = 0.35, Wald χ 2 = 5.05, p = 0.025), but the association with any 30-day disability income fell short of significance ( p = 0.082) in the same month.
