t‐ and P‐values obtained from 57 separate 2‐sample t‐tests comparing regional brain volumes between control (CON) and exposed (FASD) subjects. Hypothesis testing was conducted for CON>FASD within scan locations: Los Angeles (LA), South Africa (SA), and San Diego (SD). Bold numbers represent t‐values. For p‐values in parentheses, regular numbers represent a significant difference (p < 0.05) between groups, italicized numbers represent a trend‐level difference (0.05 < p < 0.1), and underlined numbers represent an absence of significant differences between groups.
