Study purpose

• How do the model's key biological readouts change under 68 kg, 40 years: blood group o absent, minor surgery?

Assumptions

• FVIII amounts are international biological activity units (IU); concentrations are IU/mL. No mass or generic enzyme-unit conversion is implied.
• Doses and covariates in these examples are synthetic research inputs, not patient records or dosing recommendations.
• The B-domain-deleted assay factor changes the observation only. Endogenous baseline is an observation input and contributes no administered drug.
• Alternative placements of baseline in the assay correction remain separate conditional conventions.
• Reported coefficients are used without re-estimation. Subject-effect and residual-error observers are explicit conditional completions; the original statistical fit is not reproduced.
• This model does not predict bleeding, coagulation, VWF binding or extended-half-life product behavior, and does not implement adaptive dosing.
