AIS——青少年特发性脊柱侧凸（adolescent idiopathic scoliosis）；FEV1——一秒用力呼气容积（forced expiratory volume in 1 second）；NA——未予以阐述；NNT——需治疗人数（Number Needed to Treat）；OM——结局指标（outcome measure）；QoL——生活质量（quality of life）；SIR——“脊柱侧凸住院康复”（scoliosis inpatient rehabilitation）；SR——系统综述（systematic review）；
1. 一系列更新内容，可根据作者对单个研究特征的处理方式进行合并分析或单独分析（具体说明详见补充表S1）；
2. SSE——脊柱侧凸专项运动（scoliosis specific exercise）："以矫正脊柱畸形为治疗目的的特定曲线运动"[33]；
3. OMT——整骨手法治疗（Osteopathic manipulative treatment），依据文献[7]的定义为"整骨医师通过手法引导施加治疗性力量，以改善生理功能并/或维持因躯体功能障碍而失衡的内稳态"；
4. 本研究未分析针对手术治疗患者的相关推荐意见；
5. 错𬌗（malocclusion）："上下颌闭合时牙齿位置无法完全对齐"[http://www.oxforddictionaries.com/definition/english/malocclusion]。
