Table 6.
Bivariate correlations between olfactory function (OT, OD, OI, and TDI) and each specific sub-score of CRI in men (n = 111).
| CRI-Education | CRI-Working Activity | CRI-Leisure Time | CRI-Total Score | ||
|---|---|---|---|---|---|
| OT | r | −0.346 | −0.005 | −0.105 | −0.070 |
| p | 0.001 | 0.959 | 0.111 | 0.464 | |
| OD | r | 0.164 | 0.379 | 0.333 | 0.043 |
| p | 0.085 | 0.001 | 0.001 | 0.652 | |
| OI | r | 0.194 | 0.342 | 0.334 | 0.387 |
| p | 0.042 | 0.001 | 0.001 | 0.001 | |
| TDI | r | −0.016 | 0.290 | 0.205 | 0.244 |
| p | 0.869 | 0.002 | 0.031 | 0.010 |
Legend: CRI = Cognitive Reserve Index; OT = Odor Threshold; OD = Odor Discrimination; OI = Odor Identification; TDI score = Threshold, Discrimination, and Identification score. Bold indicates statistical differences of p < 0.05.
