Bland-Altman plots of D50 compared against MC for a VSV^soft, b VSV^soft+bone, c \( {\mathrm{VSV}}_{\mathrm{weighted}}^{\mathrm{soft}} \), and d \( {\mathrm{VSV}}_{\mathrm{weighted}}^{\mathrm{soft}+\mathrm{bone}} \). The mean value of both methods was plotted against the relative difference of both methods. The blue line gives the mean relative differences and the red lines indicate the 95% limits of agreement
