- The trends in proportions were determined according to the Cochran-Armitage chi-square test
- The proportion of newborns testing positive for cannabis increased significantly (χ2 = 26.76, df = 1, p < 0.001), the proportion testing positive for benzodiazepines decreased significantly (χ2 = 13.95, df = 1, p < 0.001), and the proportions testing positive for opioids (χ2 = 1.91, df = 1, p = 0.17), cocaine (χ2 = 1.30, df = 1, p = 0.26), amphetamines (χ2 = 2.35, df = 1, p = 0.13), or methadone (χ2 = 0.004, df = 1, p = 0.95) did not change significantly. The number of barbiturate-positive tests was too low to allow evaluation
- a The totals are not equal to the sums of separate drug categories, since more than one drug could be found at the same time
