DPW during the previous 7 days was not related to any of the cognitive measures (ps >.2) and was not controlled for in any of above analyses.

All analyses with AUDIT were with n=32.

Column Key:

AUDIT = Alcohol Use Disorders Identification Test, DRINC = Drinker Inventory of Consequences Total Score, PDA = percent days abstinent, DPW = Drinks per week, Scan90 = 90 days prior to the scan visit.

Row Key:

CPTD’ = Continuous Performance Task (CPT) Detectability, CPTCom = CPT Errors of Commission, CPTOm = CPT Errors of Omission, StroopInt = Stroop Interference T Score, CPTHRT = CPT Hit Reaction Time, WTAR = Wechsler Test of Adult Reading, CPTHRTBC = CPT Hit Reaction Time Block Change, BIS = Barratt Impulsivity Scale

Correction for Multiple Comparisons:

Shaded boxes were primary variables and p-values entered into FDR correction; non-shaded boxes were not entered into FDR correction.

None were significant with FDR correction.

Transformations:

WTAR = (WTAR)⁴, CPTOm = 1/(CPTOm)³, CPTD = (CPTD’)², CPTHRT= √(CPTHRT), DPW Scan90 = ln(DPW Scan90)
