  1. Median and IQR of parameters assessed at times T1, T5, T8, T9 and ‘Cohen d’ effect size.
  2. *pFriedman = 0.059; **pFriedman < 0.05; ***pFriedman < 0.001.
  3. #pSkillings-Mack = 0.068; ##pSkillings-Mack < 0.05; ###pSkillings-Mack < 0.001.
  4. The first row lists median, the second row lists the 25%- and 75%- percentile (IQR). The lowermost row of each parameter lists significant differences to other time points (p < 0.05). (Remark: ΔCT-values are inverse to miRNA-concentrations in the samples: low ΔCT-values indicate high miRNA concentrations/high ΔCT-values indicate low miRNA concentrations).
