Multiple regression of age at onset on GAA1 size and mtDNA haplogroups
| Regression coefficient | Standard error | p< | |
|---|---|---|---|
| Age of onset is expressed in years, GAA1 size in the number of triplets; haplogroups as absent (0) or present (1). Figures are estimated regression coefficients and standard errors. | |||
| GAA1 | −0.027 | 0.002 | 0.001 |
| Haplogroup U | 5.545 | 1.550 | 0.001 |
