Figure 4. Scatter charts of values of Age, VO_2max and NDUFB9 expression levels. Graphical representation of the correlation between VO_2max and Age (A), expression levels of NDUFB9 assessed by qPCR and normalized against GAPDH (B), correlation between or VO_2max and NDUFB9 gene expression levels detected by qPCR (C). (Pearson correlation, p = 5.9 e^-6; r = 0.83 (A), p = 0.01; r = 0.55 (B), error bars, SEM * p < 0.05).
