  1. The number of newborns for whom the data was obtained is shown in parentheses
  2. a sd Standard deviation
  3. b The average length of stay among the newborns exposed to cannabis was significantly shorter than that in the opioid (t = 8.22, df = 222, p < 0.001), amphetamine (t = 6.57, df = 95, p < 0.001), and methadone (t = 5.87, df = 47, p < 0.001) groups as shown by two-sample t-tests of log-transformed LOS values. No other comparisons of length of stay were significant
