Table 2.

Day CSF sample group: means ± standard deviations and statistical comparisons between groups. * indicates significant difference (p<0.05) from control and ** indicate significant difference between High and normal 3-OMD. ANOVA is used for the comparison for all groups with pair-wise comparisons using FPLSD. The JHRLSS are only compared between normal and high 3OMD groups using t test. Gender information was unavailable for normal controls.
