  1. Mean ± SE. tested following logarithmic transformation. Pa-values derived from an independent t-test between the groups at baseline. Pb-values derived from an independent t-test between the groups at follow-up. Pc-values derived from an independent t-test between the groups at changed values. Pd-values are Pc-values adjusted with the baseline values. *P < 0.05, **P < 0.01, and ***P < 0.001 derived from a paired t-test
