我们开发并评估了用于对高血压和高脂血症患者骨关节炎（0A）的个体放射学特征的患病率和进展进行分级的量表。Baltimor Longituindal老化研究中的50名参与者的四张等时间间隔的手部X光片，他们被跟踪至少20年，由4名经验丰富的受过训练的读者单独和“盲”读。分别评估11个手关节是否存在骨赘、关节间隙狭窄、软骨下囊肿、软骨下硬化、外侧畸形和皮质塌陷，并使用Kellgren/Lawrence量表（OA的总体估计）进行分级。组内相关系数被用来确定横截面间和阅片者内的可靠性。使用寿命稳定分析评价OA进展的阅片者间一致性。除囊肿外，手部OA个体放射学特征的每个分级量表在读片者之间的横截面上都是可靠的。每位阅片员在第二次对X光片评分时，几乎可以完美地重现其原始评分。使用这些量表，不同的读者同意的所有功能的纵向进展OA的手，除了囊肿。我们认为，这种方法来分级手X线片OA已被证明是可靠的横向和纵向研究。
We developed and evaluated scales for grading the prevalence and progression of the individual radiographic features of osteoarthritis (0A) of ht and. Four equally time-spaced hand radiographs from 50 participants in the Baltimor Longituindal Study of Aging, who were followed for at least 20 years, were read separately and "blindly" by 4 experienced, trained readers. Eleven hand joints were individually assessed for the presence of osteophytes, joint space narrowing, subchondral cysts, subchondral sclerosis, lateral deformity, and cortical collapse, and were also graded using the Kellgren/Lawrence scale, a global estimate of OA. The intraclass correlation coefficient was used to determine cross-sectional inter- and intrareader reliability. Interreader agreement of OA progression was evaluated using life-stable analysis. Each of the grading scales for the individual radiographic features of OA of the hand, except for cysts, were cross-sectionally reliable between readers. Each reader was able to reproduce his original scores almost perfectly when grading the radiographs a second time. Using these scales, the different readers agreed on all the features of longitudinal progression of OA of the hand, except cysts. We believe that this method for grading hand radiographs for OA has proved to be reliable for both cross-sectional and longitudinal studies.
