Comparison of cognitive function between patients with minor/non-neuropsychiatric systemic lupus erythematosus (NPSLE), inflammatory NPSLE and ischaemic NPSLE
| Global cognitive function | Learning and memory | Executive function and complex attention | Psychomotor speed | |
| B (95% CI) | B (95% CI) | B (95% CI) | B (95% CI) | |
| Inflammatory versus minor/non-NPSLE (R) | −0.43 (−0.87 to 0.01) | −0.34 (−0.71 to 0.03) | −0.35 (−0.74 to 0.05) | −0.24 (−0.62 to 0.15) |
| Ischaemic versus minor/non-NPSLE (R) | 0.01 (−0.57 to 0.59) | 0.15 (−0.34 to 0.64) | 0.42 (−0.10 to 0.94) | 0.48 (−0.04 to 0.99) |
| Inflammatory versus ischaemic NPSLE (R) | −0.80* (−1.44 to −0.17) | −0.74* (−1.37 to −0.12) | −0.98* (−1.56 to −0.41) | −0.79* (−1.41 to −0.16) |
Data represent B’s and 95% CI’s resulting from multiple regression analyses corrected for age, sex and education. These values represent how much the (transformed) Z-score of the cognitive domain differs in the presence of a specific NPSLE phenotype. *P≤0.05.
R, reference value.
