Table 1.
Mean differences in BMI and BMI-SDS from baseline to the end of the 1-year program and to 3- and 5-year follow-up (mean (SD); N = 596; baseline observation carried forward).

−0.35 (0.41) | Mdn = −0.28 z = −17.18, P < 0.001 |
| 12th to 36th month follow-up (End of the program to 3 years after baseline) |
1.90 (2.94) | Mdn = 1.63 z = −13.80, P < 0.001 |
0.15 (0.43) | Mdn = 0.12 z = −8.76, P < 0.001 |
| 36th to 60th month follow-up (3 years after baseline to 5 years after baseline) |
