CHECK (Cohort Hip Cohort Knee) data of baseline (T0)

The Cohort Hip Cohort Knee (CHECK) is a population-based observational multicenter cohort study of 1002 individuals with early symptomatic osteoarthritis (OA) of knee and/or hip in the Netherlands. The participants were followed for 10 years. The study evaluated clinical, radiographic and biochemical variables in order to establish the course, prognosis and underlying mechanisms of early symptomatic osteoarthritis. The Dutch Artritis Foundation initiated and funded this inception cohort.This dataset covers the data collection of baseline (T0) without the variable Subject identification number. Included is a Kellgren-Lawrence radiographic classification covering T0,T2,T5, T8 and T10. Also X-rays of hips and knees of baseline are available. More information on the variables can be found in the documentation. In the description file you can find an overview of the data belonging to this dataset and more information about the format and kind of view of the X rays.The complete data are available via three separate datasets, each containing again the baseline T0 data of this current dataset. All SPSS data files of these three datasets include the variable Subject identification number.If you wish to make use of the complete CHECK data, please see the see relations for the other CHECK datasets and for the overview Thematic collection: CHECK (Cohort Hip Cohort Knee).

队列髋膝关节研究（CHECK, Cohort Hip Cohort Knee）是一项基于人群的多中心观察性队列研究，纳入荷兰1002名早发性症状性膝/髋骨关节炎（Osteoarthritis, OA）患者，随访时长为10年。本研究旨在评估临床、影像学及生化变量，以明确早发性症状性骨关节炎的病程、预后及潜在发病机制。该始发队列由荷兰关节炎基金会发起并资助。本数据集涵盖基线期（T0）的数据采集内容，但不含受试者识别编号变量。其中包含覆盖T0、T2、T5、T8及T10时间点的Kellgren-Lawrence影像学分级数据，同时提供基线期髋部与膝关节的X线影像。更多变量相关信息可查阅配套文档。在数据集说明文件中，可获取本数据集所包含数据的概览，以及X线影像的格式与成像类型相关细节。完整的CHECK研究数据集通过三个独立数据集发布，每个数据集均再次包含本当前数据集的基线T0数据。这三个数据集的所有SPSS数据文件均包含受试者识别编号变量。若需使用完整的CHECK研究数据，请查阅其他CHECK数据集的相关说明，以及主题合集《CHECK（队列髋膝关节研究）》的概览信息。
