AIP and Insulin resistance: Model 2 showed that elevated blood pressure and insulin resistance decrease the probability of being 25(OH)D3 sufficient (2.9-fold, p = 0.003 and 2.4-fold, p = 0.044, respectively); while the impact of gender, presence of central obesity, increased AIP and ln eGRF was insignificant (Omnibus test: 0.003, predicted correct classification: 76%, Cox & Snell and Nagelkarte square: 8% and 12%, respectively).
