Fig. 4. Comparisons of sagittal parameters between WSX and EOS in patients without sagittal imbalance. *Indicates significant differences in angle between WSX and EOS (p<0.05). For LL and C2-C7 Cobbs, positive values indicate lordosis and negative values indicate kyphosis. WSX, conventional whole spine X-ray; PT, pelvic tilt; SS, sacral slope; LL, lumbar lordosis (L1-S1 Cobbs angle); TPA, T1-pelvic angle; SVA, sagittal vertical axis.
