NorStOP = North Staffordshire Osteoarthritis Project; CiPCA = Consultations in Primary Care Archive; COPD = chronic obstructive pulmonary disease; HR = Hazard ratio; CI = Confidence interval.Chronic morbidity defined as consultation for ischaemic heart disease, diabetes, COPD, asthma or depression prior to baseline.a No record of i) osteoarthritis and ii) osteoarthritis or joint pain in 2001 or 2002 (comparison) or in the 2 years prior to baseline survey (NorStOP).b Adjusted for age and gender.c Adjusted for age, gender and record of joint pain in 2001 or 2002 (comparison) or in the 2 years prior to baseline survey (NorStOP).

NorStOP：北斯塔福德郡骨关节炎项目（North Staffordshire Osteoarthritis Project）；CiPCA：基层医疗咨询档案（Consultations in Primary Care Archive）；COPD：慢性阻塞性肺疾病（chronic obstructive pulmonary disease）；HR：风险比（Hazard ratio）；CI：置信区间（Confidence interval）。慢性疾病定义为基线期前因缺血性心脏病、糖尿病、慢性阻塞性肺疾病、哮喘或抑郁症就诊的情况。a 无以下记录：i) 骨关节炎；ii) 2001年或2002年（对照组）或基线调查前2年（北斯塔福德郡骨关节炎项目队列）存在骨关节炎或关节疼痛的情况。b 已针对年龄与性别进行校正。c 已针对年龄、性别，以及2001年或2002年（对照组）或基线调查前2年（北斯塔福德郡骨关节炎项目队列）的关节疼痛记录进行校正。
