an overall trendgold
When patients were matched for symptom duration (GA n=11, ACAA n=17; median 8 years from symptom onset to MR; mean age 52±7 years for both groups; mean ataxia severity GA=1.6, AA=1.5) there was an overall trend for reduced vermian NAA/Cr in the GA group compared to ACAA but this failed to reach statistical significance (0.79 vs. 0.87 respectively, CI 95% -0.19 to 0.03, p>0.05).
