UT and MT Cobb angles were measured on PA chest radiographs preoperatively and at early/final postoperative follow-up. Age, sex, number of bars (1, 2,≥3), lateral stabilizers, and retention time were recorded. Pre-vs postoperative differences were tested with paired t-tests; intersegment and covariate associations with Pearson correlation (P \u003C .05).  \nResults: Age was 17.1 ± 4.9 (PE) and 16.6 ± 7.9 (PC). In PE, UT/MT angles rose from 7.12􀀎/7.03􀀎 (95% CI, 7.01􀀎 -8.98􀀎/6.29􀀎 -8.33􀀎 ) to 8.47􀀎/  \n7.20􀀎 (95% CI, 8.43􀀎 -10.67􀀎/6.23􀀎 -8.43􀀎 ); UT increased in 79.2% and MT in 49.2%. In PC, UT rose from 4.5􀀎 (95% CI, −1.47􀀎 to 18.41􀀎 ) to 6.73􀀎 (95% CI, −2.22􀀎 to 22.39􀀎 ), while MT fell from 10.02􀀎 (95% CI, 1.45􀀎 -12.38􀀎 ) to 9.97􀀎 (95% CI, 3.2","cbCaigKulBwDuKLN","https://ap.wps.com/l/cbCaigKulBwDuKLN","pdf",1065656,"English","# Abstract\n## Objectives\n## Methods\n## Results\n## Conclusions\n## Keywords\n# Introduction","[{\"question\":\"What was the primary objective of this retrospective cohort study?\",\"answer\":\"To evaluate segmental changes in thoracic spinal alignment after minimally invasive bar correction in PE and PC patients, and to determine relationships between upper thoracic and main thoracic curvature changes and clinical or surgical factors.\"},{\"question\":\"How were thoracic alignment changes measured and compared?\",\"answer\":\"UT and MT Cobb angles were measured on PA chest radiographs before surgery and at early and final postoperative follow-up.
