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

Stage necrotizing enterocolitis severity using modified Bell criteria across systemic, intestinal, and radiologic findings to guide medical versus surgical management decisions

Each component has a specific meaning:

  • Modified Bell criteria across systemic — The modified bell criteria across systemic recorded for the scenario being assessed.
  • Intestinal — The intestinal recorded for the scenario being assessed.
  • Radiologic findings — The radiologic findings recorded for the scenario being assessed.

Note: Interpret the nec bell staging result against the thresholds and context described above.
