Correlation matrices were constructed for various human skin variables (propionibacteria, micrococcaceae, sebum excretion rate, percentage of free fatty acids and free fatty acid production rate). Two independent populations were studied (n = 87 and n = 103), and a subpopulation (n = 30) was investigated on three occasions at intervals of I month. In this way consistently high correlations could be differentiated from 'fortuitous' correlations. Propionibacteria versus micrococcaceae showed the highest correlation coefficient and propionibacteria versus percentage free fatty acids was also highly correlated. A scatter diagram indicated a relationship between the lower threshold of microbial density and sebum excretion rate. An explanation based on relative duct and gland size is presented.
构建了各种人体皮肤变量（丙酸杆菌、微球菌科、皮脂分泌率、游离脂肪酸百分比和游离脂肪酸生成率）的相关矩阵。研究了两个独立的群体（n = 87和n = 103），并对一个亚群体（n = 30）每隔1个月进行三次调查。通过这种方式，可以将始终较高的相关性与“偶然”相关性区分开来。丙酸杆菌与微球菌科显示出最高的相关系数，丙酸杆菌与游离脂肪酸百分比也高度相关。散点图表明微生物密度下限与皮脂分泌率之间存在关系。提出了基于相对导管和腺体大小的解释。
