Figure 3. Case study. The figure illustrates the use of the reference centiles. First, the two 1MWT scores are entered (three crosses, 34 m at M0, age1 = 5 years 11 months, 46 m at M6, age2 = 6 years 5 months, and 51 m at M12, age3 = 6 years 11 months). The corresponding Z-scores are Z1 = −1.146 for M0, Z2 = −0.773 for M6 and Z3 = −0.652 for M12. The age-dependant standard deviation (SD1) of the centile change, is determined by using the dashed curve and the age of the child at the first 1MWT assessment at M0 (SD1 = 0.761) and at M6 (SD2 = 0.758). Using the formula (Z2-Z1)/SD1, the Z-score for the centile change can be calculated. It corresponds to an effect size (−0.773 + 1.146)/0.761 = 0.49 for the first 6 months, during the active training in the rehabilitation program ‘Auf die Beine’. During the observational 6-month period (Z3-Z2)/SD2 = 0.16 corresponding to a negligible effect size.
