由13名观察员使用4种不同的异常评分方法读取了16例类风湿性关节炎患者的41张编码X线片。虽然个体观察者之间的绝对评分差异很大，但3次比较中约有2次的相关系数大于0.850。当使用所有读者的中位数排名对电影进行排名时，72%的个人排名在中位数排名的10%以内。在个别患者的系列电影中，92%的早期和晚期电影之间的比较被解释为显示异常进展时，平均标准化评分显示评分增加15个单位或更多。变化较小的电影解释不一致。本研究显示，当应用于显示广泛严重程度的胶片集时，阅片者在手部和手腕的放射学异常评分方面具有良好的普遍一致性，并定义了疾病进展的放射学检测的灵敏度。
Forty‐one coded radiographic films from 16 patients with rheumatoid arthritis were read by 13 observers, using 4 different methods for scoring abnormalities. Although absolute scores differed widely among individual observers, correlation coefficients were greater than 0.850 for approximately 2 of 3 comparisons. When films were ranked, using the median rank of all readers, 72% of individual ranks were within 10% of the median ranks. Among serial films on individual patients, 92% of comparisons between early and late films were interpreted as demonstrating progression of abnormalities when mean standardized scores showed an increase in scores of 15 units or greater. Films with lesser changes were interpreted inconsistently. This study shows good general agreement among readers in scoring radiologic abnormalities of hands and wrists, when applied to a film set showing a broad spectrum of severity, and defines the sensitivity of radiologic detection of disease progression.
