Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Predict 1, 2, 3-year mortality in IPF using GAP model: Gender, Age, Physiology (FVC, DLCO). GAP index 0-8

Each component has a specific meaning:

  • GAP model: Gender — The gap model: gender recorded for the scenario being assessed.
  • Age — The age recorded for the scenario being assessed.
  • Physiology (FVC — The physiology (fvc recorded for the scenario being assessed.
  • DLCO) — The dlco) recorded for the scenario being assessed.

Note: Interpret the ipf gap model result against the thresholds and context described above.

How to Use

Enter the GAP model: Gender, Age, Physiology (FVC, DLCO) for the scenario you are assessing. Predict 1, 2, 3-year mortality in IPF using GAP model: Gender, Age, Physiology (FVC, DLCO). GAP index 0-8. Use the ipf gap model result to inform your calculation.
