Figure 7From: Blood profile holds clues to role of infection in a premonitory state for idiopathic parkinsonism and of gastrointestinal infection in established diseaseEstimated odds ratio, with 95% CI, in subjects without clinically-definite parkinsonism, for presence of a given sign, if serum immunoglobulin concentration doubled. Concentrations adjusted to age 60 years and as if all subjects male. Statistical significance of associations with bradykinesia and postural abnormality are, for IgM p = 0.001 & 0.8; for IgG 0.02 & 0.003; for IgA 0.001 & 0.001; for IgA1 0.004 & 0.001; for IgA2 0.2 & 0.07, respectively. Regarding rigidity, presence of activation phenomenon associated with IgA (OR = 1.7 (1.1, 2.6), p = 0.01) and IgA1 (1.6 (1.1, 2.3), p = 0.02).Back to article page
