Proportions of negative UCTs by gender and SOCRATES – Taking Steps.

Note: Estimated marginal means represented in figure reflect interaction of gender by Taking Steps on proportion of negative UCTs. SOCRATES – Taking Steps median split was used to illustrate interaction. Women low in Taking Steps had greater proportion of negative UCTs (M = .11, SE = .15) than women high in Taking Steps (M = .01, SE = .01); OR = .08(.02-.37), p = .001, while among men there was no significant difference by level of Taking Steps [low M = .08, SE = .09 vs. high M = .07, SE = .08; OR = .91(.37-2.24), p = .84]. Proportion neg. UCTs reflects the number of negative urine cannabinoid tests over the total number of UCTs during the study period, adjusted for non-independence.
