协调队列间的数据对于验证结果或在Meta分析中合并数据非常重要。我们复制和验证以前的转换莫卡MMSE PD。我们使用了五项研究，其中包括1，161名PD个体和2，091名莫卡和MMSE测量的观察结果。我们比较了先前发布的转换表，使用等百分位数等同对数线性平滑与我们内部推导的分数。当比较真实和转换的MMSE时，两种转换都发现研究内和研究间具有良好的一致性（平均差异：0.05;标准差：1.84;中位数差异：0;四分位数范围：-1至1，使用内部转换）。这些结果表明，人们可以得到一个可靠的和有效的转换之间的两个常用的认知措施在PD研究。这些方法需要应用于其他尺度和领域，以实现跨多个PD队列的大规模协作分析。© 2016国际帕金森和运动障碍协会
Harmonizing data across cohorts is important for validating findings or combining data in meta‐analyses. We replicate and validate a previous conversion of MoCA to MMSE in PD. We used five studies with 1,161 PD individuals and 2,091 observations measured with both the MoCA and MMSE. We compared a previously published conversion table using equipercentile equating with log‐linear smoothing to our internally derived scores. Both conversions found good agreement within and across the studies when comparing true and converted MMSE (mean difference: 0.05; standard deviation: 1.84; median difference: 0; interquartile range: –1 to 1, using internal conversion). These results show that one can get a reliable and valid conversion between two commonly used measures of cognition in PD studies. These approaches need to be applied to other scales and domains to enable large‐scale collaborative analyses across multiple PD cohorts. © 2016 International Parkinson and Movement Disorder Society
