At 8-year follow-up of 103 patients with rheumatoid arthritis, an X-ray index based on Larsen's score for the hands, wrists, ankles and feet showed a high correlation with the joint score (0.75 by Spearman's rank correlation), the function score (0.68), ESR (0.61), and CRP (0.64). These results suggest that Larsen's method of scoring both the hands and feet is a valid single method to assess long-term outcome in rheumatoid arthritis.
对103例类风湿关节炎患者进行8年随访，基于拉森评分法对手、腕、踝和足部进行的X线指数与关节评分（Spearman等级相关系数为0.75）、功能评分（0.68）、红细胞沉降率（0.61）及C反应蛋白（0.64）高度相关。这些结果表明，拉森对手部和足部的评分方法是评估类风湿关节炎长期预后的一种有效的单一方法。
