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

Apply DAWN trial selection criteria for thrombectomy in 6-24 hour window using DWI volume and NIHSS clinical mismatch

Each component has a specific meaning:

  • DWI volume — The dwi volume recorded for the scenario being assessed.
  • NIHSS clinical mismatch — The nihss clinical mismatch recorded for the scenario being assessed.

Note: Interpret the dawn mismatch result against the thresholds and context described above.

How to Use

Enter the DWI volume, NIHSS clinical mismatch for the scenario you are assessing. Apply DAWN trial selection criteria for thrombectomy in 6-24 hour window using DWI volume and NIHSS clinical mismatch. Use the dawn mismatch result to inform your calculation.
