Linear regression beta-coefficients for cerebrospinal fluid (CSF) Aβ42 levels in cognitively normal control subjects (Controls: grey circle) or Parkinson’s disease patients (PD: black square) for each collapsed genotype. A confidence interval that does not cross the vertical line at zero indicates that the difference in genotype is significant (p < 0.05) before adjusting for multiple comparisons as indicated by asterisk (*). A beta coefficient to the left of the vertical line indicates lower CSF Aβ42 levels for the collapsed genotype group (EE, EF) than for the major homozygote genotype (FF). Beta coefficients, 95% confidence intervals and p-values in parentheses are not adjusted for covariates.
