The structural model of1 was trained on data from naïve subjects, but is appropriate to use for data from convalesced individuals as well. The RMSE of the model fit to data is no larger than the RMSE for the fit to data from naïve individuals. Median RMSE for the fit to the naïve population data is 0.026, with quartiles [0.017, 0.037]. Median RMSE fit to the convalesced population data is even lower at 0.016, with quartiles [0.005, 0.024].
