Predictive value of BIA and BMI towards DXA.
| | | DXA | | | | Nonobese (FM < 25% M, < 35% F) | Obese (FM ≥ 25% M, ≥ 35% F) | |
| BMI | <30 kg/m2 ≥30 kg/m2 | 2 0 | 53 48 | Overall predictive value: 48.5% Sensitivity: 47.5% Specificity: 100% Positive predictive value: 100% Negative predictive value: 3.6% |
| BIA | Non-obese (FM 25% M, 35% F) Obese (FM 25% M, 35% F) | 2 0 | 15 85 | Overall predictive value: 85.3% Sensitivity: 85% Specificity: 100% Positive predictive value: 100% Negative predictive value: 11.8% |
