Note: measures for Trail A, Trail B, SRT, and CRT represent response time. Thus, positive β values indicate poorer performance relative to no diabetes group. All other measures (MMSE, SDMT, Imm. Rec., STW, Digit Back., and PPEG (both hands)) represent number of items completed correctly (negative β values indicate poorer performance).
