Levels of biomarkers across the diagnostic groups. A Combined boxplots and scatter plots showing the CSF activity of PKM (mU/mL) and ALDO (mU/mL) and the concentration of FABP3 (pg/mL) and UCHL1 (pg/mL) in the diagnostic groups presented as median and interquartile range. Analysis was performed by ANCOVA. Symbols indicate the significant comparisons versus SCD ($), MCI (*) and FTD (#). The number of symbols indicates the level of statistical significance: p < 0.05, p < 0.01, p < 0.001. B Correlation plot (Spearman) for the CSF biomarkers panel in the whole cohort. White colour indicates no significant correlation
