Appendix B
Data Comparison Between Moskowitz and Robinson(1988) and
Moskowitz and Fiorentino(1999)
Impairment in experimental studies was found more frequently at lower BACs in this review than in Moskowitz and Robinson (1988). This can be clearly seen across all behavioral areas.
In the following section, we examined the number of studies for each behavioral area from Moskowitz and Robinson (1988) and the current review. The results from Moskowitz and Robinson (1988) have been rearranged to fit into the BAC breakdown of the current study (i.e., ending in zero rather than 9). Tables B1 and B2 report the number of studies reporting impairment by lowest BAC at which impairment was found for the Moskowitz and Robinson (1988) and the current study, respectively.
Note that here we are looking at the number of studies at each behavioral area. Most studies are represented in more than one behavioral area, thus the total number of behavioral areas by study increases to 221 and 150 for Moskowitz and Robinson (1988) and the current review, respectively. This is less than the number of BACs at which the behavioral areas are examined in section 3.2. and figures 3 and 4.
