Table 5. Predictive performance of three models in 10-fold cross-validation.

	Mapping Models for EQ-5D-5L scores
	Model 1	Model 2	Model 3
Predictive performance
RMSE	0.065	0.062	0.063
MAE	0.044	0.039	0.039
AE > 0.05	32.8%	30.7%	30.3%
AE > 0.10	13.8%	11.7%	11.7%

Note: EQ-5D-5L = EuroQoL 5-dimension 5-level; RMSE = root mean square error; MAE = mean absolute error; AE = absolute error
