Additional analyses probing sink activities associated with factor 600 (cf. Fig. 6C, row 4) at inferior sites revealed several significant effects. A marginal group × intensity interaction at mid-anterior sites (Nz, Nose; F[2, 74] = 3.02, p = .06, ε = 0.9245) originated from a reduced sink to weak (−0.72 ±1.07) compared to medium (−1.29 ±0.95) and strong (−1.25 ±1.26) odor intensities in patients (simple intensity main effect, F[2, 74] = 3.19, p = .05, ε = 0.9245), which was not observed for controls (F[2, 74] < 1.0; cf. Fig. 6B, rows 3 and 4). In contrast, a significant group × intensity interaction at lateral frontotemporal sites (F9/10, FT9/10; F[2, 74] = 4.06, p = .03, ε = 0.8863) stemmed from a monotonic sink increase with odor intensity in controls (F[2, 74] = 3.28, p = .05, ε = 0.8863) but not patients (F[2 74] = 1.46, p > .24, ε = 0.8863; cf. Fig. 6B, rows 3 and 4). This analysis also revealed a significant main effect of hemisphere, F(1, 37) = 10.5, p = .01, stemming from a
