Interestingly, the conventional Pearson’s correlations computed among participants between OERP measures and odor detection, each pooled across odor intensity, revealed significant associations for patients (dL with N1 sink, left vs. right hemisphere, r = −0.45 vs. −0.47, both p = 0.02; with P2 source, r = 0.70, p < 0.001), but not for controls (r = −0.23, −0.22, and −0.13, respectively; all p > 0.16). Thus, patients having larger N1 and P2 had higher odor detection scores.
