Coefficients for multiple regression models among caucasiansa
| Marker(predictor)/test (outcome) | Inflammatory marker: test for trendb (p-value) | Marker quartile 2 vs 1c | Marker quartile 3 vs 1 | Marker quartile 4 vs 1 |
|---|---|---|---|---|
| IL8/Recall a Pattern | −1.7 ± 2.3 (0.45) | −157.1 ± 55.5 | −.3.0 ± 55.8 | −72.0 ± 55.6 |
| IL8/Digit Symbol Substitution | 2.1 ± 2.5 (0.41) | −54.9 ± 62.0 | 8.5 ± 62.2 | 22.9 ± 62.1 |
a
All models adjust for Age, Gender, and Education.
b
A positive coefficient indicates that higher levels of the marker are associated with longer (slower) reaction times, measured in milliseconds. No categorical variables for markers in this model.
c
Cutpoints for quartiles determined by dividing the population into four equal-sized groups. No continuous variable for marker in this model.
