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

Score pemphigus vulgaris activity using PDAI (Pemphigus Disease Area Index): skin activity (0-250), scalp activity (0-10), mucous membrane activity (0-40). Severe >45

Each component has a specific meaning:

  • PDAI : skin activity — The pdai : skin activity recorded for the scenario being assessed.
  • Scalp activity — The scalp activity recorded for the scenario being assessed.
  • Mucous membrane activity — The mucous membrane activity recorded for the scenario being assessed.

Note: Interpret the pdai pemphigus score result against the thresholds and context described above.

How to Use

Enter the PDAI : skin activity, scalp activity, mucous membrane activity for the scenario you are assessing. Score pemphigus vulgaris activity using PDAI (Pemphigus Disease Area Index): skin activity (0-250), scalp activity (0-10), mucous membrane activity (0-40). Severe >45. Use the pdai pemphigus score result to inform your calculation.
