n | 86 | 165 | |

Significant VHD | 21 (24%) | 15 (9%) | 0.002 |

Sensitivity | 57% (34%–78%) | 27% (8%–55%) | 0.40 |

Specificity | 71% (58%–81%) | 69% (61%–76%) | 0.99 |

Positive predictive value | 39% (22%–58%) | 8% (2%–19%) | 0.01 |

Negative predictive value | 84% (71%–92%) | 90% (83%–95%) | 0.84 |

Positive likelihood ratio | 1.95 (1.15–3.32) | 0.85 (0.36–2.04) | 0.11 |

Negative likelihood ratio | 0.61 (0.36–1.02) | 1.07 (0.77–1.48) | 0.07 |

P values are for the differences between groups (BMI <25 vs ≥25) and are based on χ

^{2}test, with the exception of Cochran’s Q test for likelihood ratios.
