Table 2 Mean changes in metabolic health indicators pre- and post-training in the intervention group and chances that the true difference in the changes is substantial (n = 43)

From: Age and menarcheal status do not influence metabolic response to aerobic training in overweight girls

  Pre-training Post-training Changes in mean, 90% CL (%) Coefficient of variation, 90% CL (%) Practical inference
Height (cm) 158.9 (8.2) 159.9 (8.0) 0.7 (0.5 to 0.9) * 0.6 (0.5 to 0.7) Probably trivial
Body mass (kg) 76.6 (14.7) 75.7 (14.6) -1.1 (-2.0 to -0.3) * 2.3 (2.0 to 2.8) Probably trivial
BMI (kg/m2) 30.1 (4.0) 29.4 (4.0) -2.5 (-3.2 to -1.7) * 2.1 (1.8 to 2.6) Probably trivial

Total CT (mg/dl) 159.3 (31.2) 159.6 (31.6) 0.3 (-2.5 to 3.2) 8.2 (6.9 to 10.1) Possibly trivial
HDL-C (mg/dl) 43.1 (8.2) 50.3 (9.4) 17.0 (11.9 to 22.3) * 13.0 (10.9 to 16.1) Benefit likely
LDL-C (mg/dl) 92.4 (26.0) 91.0 (24.5) -0.4 (-5.9 to 5.4) 16.8 (14.1 to 20.9) Unclear
TG (mg/dl) 120.9 (64.3) 93.3 (47.9) -22.7 (-29.6 to -15.1) * 29.5 (24.6 to 37.1) Benefit possible

Insulin (μIU/ml) 16.9 (7.6) 15.6 (9.8) -14.1 (-24.1 to – 2.9) ** 40.6 (33.6 to 51.6) Benefit possible
HOMA-IR 3.691 (1.750) 3.412 (2.121) -12.7 (-22.9 to -1.2) 40.8 (33.7 to 51.8) Benefit possible
