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

Quantify absolute benefit of IV tPA versus placebo from NNT data stratified by baseline NIHSS and time-to-treatment

Each component has a specific meaning:

  • NNT data stratified by baseline NIHSS — The nnt data stratified by baseline nihss recorded for the scenario being assessed.
  • Time-to-treatment — The time-to-treatment recorded for the scenario being assessed.

Note: Interpret the mrs thrombolysis result against the thresholds and context described above.

How to Use

Enter the NNT data stratified by baseline NIHSS, time-to-treatment for the scenario you are assessing. Quantify absolute benefit of IV tPA versus placebo from NNT data stratified by baseline NIHSS and time-to-treatment. Use the mrs thrombolysis result to inform your calculation.
