Mitochondrial respiration corrected for mitochondrial content. a Whole group (n = 28). b Positive responders (n = 8). c Negative responders (n = 8). For explanations of the variables see legend Table 2. Values are mean and standard error of the mean. p values are calculated by paired t-test within groups and analysis of covariance (ANCOVA) between subgroups of negative and positive responders. *(p < 0.05), **(p < 0.01)
