Cognitive score comparisons between heavy smokers and nonsmokers
| Nonsmokers (n=24) | Heavy smoker (n=20) | t, z, or χ2 | P-value | |
|---|---|---|---|---|
| PASAT | 40.04±35.27 | 33.40±32.80 | z=0.562 | 0.574 |
| SRT | 45.17±10.32 | 45.25±8.38 | t=0.029 | 0.977 |
| SRT-DR | 7.33±2.58 | 6.60±3.36 | t=0.818 | 0.418 |
| SPART | 16.13±5.15 | 14.50±6.71 | t=0.909 | 0.369 |
| SPART-DR | 5.25±1.75 | 4.75±2.34 | t=0.811 | 0.422 |
| SDMT | 31.58±15.87 | 28.95±10.54 | z=0.602 | 0.547 |
| WLG | 17.92±3.74 | 19.05±5.39 | t=0.820 | 0.417 |
| Cognitive impairment (%) | 29.2 | 60.0 | χ2=4.227 | 0.04 |
Notes: Data are expressed as the mean ± standard deviation unless otherwise specified. Patients scoring in the fifth percentile or less in at least two of these tests were considered to have cognitive impairment according to the normative data from the general Turkish population. Bold indicates a statistically significant P-value.
