Potential power scenarios, depending on the proportion of events in the two vitamin D groups, when taking potentially varying proportions of hypovitaminosis D in the cohort into account
| Potential percentage with any cardiovascular event in the group having vitamin D < 50 nmol/L (%) | Potential percentage with any cardiovascular event in the group having vitamin D ≥ 50 nmol/L (%) | Potential weighting Patients with vitamin Dtotal < 50 nmol/L: Patients with vitamin Dtotal ≥ 50 nmol/L | Power |
