The incidence of finger pattern types and the pattern intensity distribution in a Spanish sample (417 males and 416 females) drawn from the geographical area of Tierra de Campos have been studied. Sexual and bilateral differences for both dermatoglyphic traits were explored by means of chi 2-test and Mann-Whitney U-test, showing significant differences in all cases, excepting the sexual difference between left hands for pattern intensity. Kolmogorov test for distribution normality showed that pattern intensity was not normally distributed, being the distributions right skewed because of the low frequency of classes with fewer triradii. The results obtained in Tierra de Campos were compared with those observed in other Spanish and Portuguese populations, showing more heterogeneity in the pattern types than in pattern intensity. This could imply that arches account for the main source of variation between populations. Moreover, pattern type frequencies and pattern intensity in Tierra de Campos are, as expected, within the variation ranges of Southeuropean-Mediterranean populations and Caucasians as a whole, although the incidence of radial loops is located in the lower extremes of the corresponding variation ranges.
对从坎波斯地区抽取的一个西班牙样本（417名男性和416名女性）的指纹类型发生率和纹型强度分布进行了研究。通过卡方检验和曼-惠特尼U检验探讨了这两种皮纹特征的性别差异和双侧差异，结果显示在所有情况下均存在显著差异，但左手纹型强度的性别差异除外。分布正态性的柯尔莫哥洛夫检验表明，纹型强度并非正态分布，由于三叉点较少的类别出现频率较低，其分布呈右偏态。将在坎波斯地区获得的结果与在其他西班牙和葡萄牙人群中观察到的结果进行比较，结果显示纹型类型比纹型强度具有更多的异质性。这可能意味着弓形纹是人群间变异的主要来源。此外，正如预期的那样，坎波斯地区的纹型类型频率和纹型强度处于南欧-地中海人群以及整个高加索人群的变异范围内，尽管桡侧箕纹的发生率位于相应变异范围的下限。
