Z-Scores 是以标准差单位来表现的一组观察值。它是将观察值减去该组观察值的中值，再除以标准差得到的。通过将观察值的分布转换成Z-SCORES 分布，一个中值为0，标准差为1的新分布被列出了。percentile 统计学术语，如果将一组数据从小到大排序，并计算相应的累计百分位，则某一百分位所对应数据的值...

Understanding the ocular structural changes are fundamental to defining strategies for myopia prevention and management. This study aimed to establish age-gender specific normative LMS parameters for axial length to generate percentile and Z-score growth
The LMS method was used for the calculation of LMS parameters and the generation of percentile and Z-score growth curves for axial length. Growth curves derived from the LMS parameters were compared with those originally calculated. Axial elongation was age- and percentile-dependent. The highest ...
