Values are presented as mean (SD), median [IQR], or N (%). Bold values indicate p-values significant at <0.05.
Pairwise comparisons were examined using Tukey's HSD (α = 0.05) for continuous outcomes or Bonferroni adjustments (α = 0.05/3 = 0.0167) for dichotomous outcomes.
Used as an indicator of education quality.
Other SUDs include alcohol, cannabis, cocaine, hallucinogens, opioids, PCP, and sedatives.
Plasma; defined as >50 copies/mL.
Values were compared by Wilcoxon Test because of skewed distributions.
dx, diagnosis; HSD, honestly significant difference; IQR, interquartile range; LT, lifetime; PCP, phencyclidine; SD, standard deviation; SUD, substance use disorder; WRAT-reading, wide range achievement test, reading subtest.
