  • 4-150 Washinton DC was excluded because of the rates in that district being an outlier.

  • 4-151 Parameter estimates and standard errors are for the transformed dependent variable ln (average rate + 0.05).

  • 4-152 Significant with p < 0.05 for all articles and articles categorised by policy type; degrees of freedom for F test are 1 and 47 for ASSIST and IOI score, and 4 and 192 for year and ASSIST–year interaction.

  • 4-153 ASSIST states include Colorado, Indiana, Massachusetts, Maine, Michigan, Minnesota, Missouri, North Carolina, New Jersey, New Mexico, New York, Rhode Island, South Carolina, Virginia, Washington, Wisconsin, and West Virginia.
