Adverse change (AC) thresholds based on the control group’s approximate 5th percentile.
AC thresholda | Controls meeting proposed AC threshold | Exercisers meeting proposed AC threshold | p-valueb | |
---|---|---|---|---|
Insulin | ≥ 39 pmol/L | 12/289 (4.2%) | 30/676 (4.4%) | 0.40 |
Triglycerides | ≥ 0.95 mg/dL | 15/315 (4.8%) | 22/754 (2.9%) | 0.16 |
HDL-C | ≥ 0.36 mmol/L | 13/315 (4.1%) | 25/755 (3.3%) | 0.56 |
SBP | ≥ 21 mm Hg | 12/243 (4.9%) | 21/562 (3.7%) | 0.46 |
The AC thresholds correspond to the upper 5th percentile in the adverse direction of the control group’s observed changes. The 5th percentile corresponds to approximately and not exactly 5% of the control subjects due to there being ties in the baseline-to-follow-up changes in the control group and the fact that the number of control subjects is not a multiple of 20 since 0.05 = 1/20.
Negative hypergeometric distribution two-sided p-value that the exercise group AC rate is different from the control group AC rate.
