Tibbling等报告98例正常人,其年龄和脑脊液总蛋白之间有肯定的关系(r=0.54,P<0.001)。作者研究41例运动神经元疾病患者,其中38例诊断经病理学确定。此组病人,腰椎穿刺的年龄和脑脊液总蛋白(平均数0.59±0.34)之间有一个否定的关系(r=0.31,P<0.05)。达两个关系系数之间的差别 Tibbling et al. Reported 98 normal subjects with a positive relationship between age and CSF total protein (r = 0.54, P <0.001). The authors studied 41 patients with motor neuron disease, of which 38 were diagnosed pathologically. There was a negative relationship between the age of lumbar puncture and total protein in cerebrospinal fluid (mean 0.59 ± 0.34) in this group of patients (r = 0.31, P <0.05). The difference between the two relationship coefficients
