A population model can describe average covariate effects without eliminating individual variability.
The model used concentration and response data from twenty studies and 933 people aged six to ninety-three. Simulated administration targeting sedation or a BIS endpoint declined with advancing age, consistent with selected clinical observations. ICU and extracorporeal-support data received additional analysis.
The model combines heterogeneous studies and response measures. Predicted effect-site exposure is not a direct measurement, and a simulated target is not validated for every patient or endpoint. Extreme illness may require particular caution in extrapolation.
Specify the model, covariates and target when presenting a prediction. It cannot establish a person’s actual concentration, consciousness or optimal dose from age alone. A forensic reconstruction requires known delivery, clinical observations and uncertainty rather than treating the modeled trajectory as sampled blood data.
