Note: This table combines statistical results for dichotomous variables and also variable with multiple responses. The Chi squared and degrees of freedom columns apply to the dichotomous variables, and the WW and Gehan's test statistic columns apply to variables with multiple categories. Drug levels in urine have been "simplified" or combined into composite trivariate categories to aide statistical analysis by combining levels of ++ to ++++ as simply ++. Parameters are presented as ordered by significance of the P-value.
