**2.4. Statistical analysis**

The post-intervention Cobb angles, the coronal offset, sacral slope, pelvic tilt, pelvic incidence, L1-S1 lordosis, T10-L2 kyphosis, T4-12 kyphosis, the pelvic incidence-lumbar lordosis (PI-LL) mismatch, and C7-S1 SVA were compared to the baseline measurements. Paired t tests were conducted to determine whether the post- and pre-intervention difference was statistically significant at *p* < 0.05. Similar statistical analysis was performed for ATR as well as SRS-22 domain scores.
