Table 2. Cross-sectional correlations between leukocyte populations and amyotrophic lateral sclerosis (ALS) Functional Rating Scale-revised (ALSFRS-R) score and disease progression rate, a cohort study of 288 ALS patients in Stockholm, Sweden*.
Cell type | ALSFRS-R | Progression rate | ||||
---|---|---|---|---|---|---|
Coefficient | p value | FDR | Coefficient | p value | FDR | |
Leukocyte (109/l) | −2.80 | 4.0E−03 | 0.01 | 0.02 | 0.74 | 0.74 |
Neutrophil (109/l) | −3.10 | 1.0E−03 | 4.0E−03 | 0.05 | 0.33 | 0.67 |
Lymphocyte (109/l) | 1.48 | 0.15 | 0.15 | −0.08 | 0.32 | 0.67 |
Monocyte (109/l) | −2.75 | 2.0E−03 | 4.0E−03 | −0.03 | 0.52 | 0.69 |
Bold values denote statistical significance of p < 0.05.
Generalized estimating equation model was applied to derive the coefficient estimates and p values, with adjustment for age at diagnosis and sex. ALSFRS-R score ranges from 0 to 48, with higher score showing better motor function status. Progression rate indicates the decline of motor function per month.
FDR: false discovery rate.
