Table 5. Data modification scoring.

Model	Modification	Range (days)	Days per knot	Target	Calibration (95%)	Bias	Interval score
parametric	none	60	14	onset date	0.96	0.141	1.41*
parametric	data driven*	60	14	onset date	0.94	0.0352*	2.02
parametric	none	60	14	specimen date	0.91	-0.136	3.77
parametric	data driven*	60	14	specimen date	0.94*	-0.0604*	3.67*

* indicates the best performing model in each pair.
