R1, % of the absolute error predicted by the model; R2, % of the square error predicted by the model; 95% CI, 95% central intervals; OLS, ordinary least squares; CLAD, censored least absolute deviation; TPM, two-part model; TPM-L, two-part model with log-transformed EQ-5D index; LCM, latent class model.
