The type of onset in 235 patients with rheumatoid arthritis (RA) was acute in 69, subacute in 55, and gradual in 111 patients. The radiological destruction of the hands and feet after 7 years from the beginning of the disease was the same in all patient groups. Thus the nature of the onset of RA seems not to have any significant influence on the outcome of the arthritis.
235例类风湿关节炎（RA）患者中，69例起病急，55例亚急性起病，111例起病缓慢。从疾病开始7年后，所有患者组的手足放射学破坏情况相同。因此，RA的起病性质似乎对关节炎的结局没有任何显著影响。
