Additional file 1 of Development of a radiographic scoring system for new bone formation in gout

Additional file 1: Figure S1. PRISMA flow diagram for literature review. Table S1. Frequency of the most commonly used scoring systems that assess any feature of new bone formation (n = 840 papers)a. Data are presented for the most frequently used radiographic scoring systems (> 5 articles). Table S2. Measurements for the first development exercise of individual joint analysis scoring. Table S3. Clinical features of the 20 participants in development exercise. Unless stated, data are presented as mean (SD). Table S4. Clinical features of the 25 participants with full scoring exercise. Unless stated, data are presented as mean (SD). Table S5. Intraclass correlation coefficient (ICC) for the first development exercise. ICC, intraclass correlation coefficient; CI, confidence interval; BLOKS, Boston Leeds Osteoarthritis Knee Score; PARS, Psoriatic Arthritis Ratingen Score. Table S6. Spearman correlation coefficients for baseline visit gout characteristics and new bone formation scores in the full scoring exercise. Table S7. Spearman correlation coefficients for changes in gout outcomes and new bone formation scores in the full scoring exercise over the Year 2 study period. Data are shown as Spearman correlation coefficient (P value).

补充材料1：图S1。用于文献综述的PRISMA（系统评价与Meta分析优先报告条目）流程图。表S1：评估新骨形成任意特征的最常用评分系统使用频次（纳入文献共840篇）a。数据针对使用频次最高的影像学评分系统（纳入文献≥5篇）进行展示。表S2：单项关节分析评分首次开发演练的测量指标。表S3：开发演练中20名参与者的临床特征。除特别说明外，数据以均值（标准差，SD）表示。表S4：完成完整评分演练的25名参与者的临床特征。除特别说明外，数据以均值（标准差，SD）表示。表S5：首次开发演练的组内相关系数（intraclass correlation coefficient, ICC）。术语说明：ICC即组内相关系数；CI即置信区间；BLOKS为波士顿利兹膝骨关节炎评分；PARS为银屑病关节炎雷廷根评分。表S6：完整评分演练中基线随访痛风特征与新骨形成评分的斯皮尔曼（Spearman）相关系数。表S7：完整评分演练中，研究第2年随访周期内痛风转归变化与新骨形成评分的斯皮尔曼（Spearman）相关系数。数据以斯皮尔曼相关系数（P值）形式展示。
