UNASSIGNED: A total of 500 cases were investigated for \"ATD\" angle and patterns, of which 250 subjects of smokeless tobacco are assessed for statistical significance via comparing them to 250 subjects of nonconsumers. Student\'s t-test was employed for evaluating quantitative factors (also known as the \"ATD\" angle), and the Chi-square test was used to analyze qualitative variables (also known as fingerprint patterns). A P value of 0.05 or less was considered significant.
UNASSIGNED: In this study, the angle \"ATD\" was found to be reduced in both the palms of males (P 0.001) and females (P 0.001) when compared to controls, which was statistically highly significant. In our study, we discovered that the number of whorls and arches is lower in male cases as compared to male controls, which is highly significant (P = 0.020 and P = 0.010). Male cases had a greater number of loops than male controls, which was statistically significantly greater (P 0.001).
UNASSIGNED: In this latest study, an association between smokeless tobacco users and palmar dermatoglyphics was identified. Though dermatoglyphics solely is unable to identify individuals who abuse alcohol and/or cigarette packs, the results of this research could serve to further develop diagnostic guidelines.
■共调查了500例“ATD”角度和模式,其中250名无烟烟草受试者通过与250名非消费者受试者进行比较来评估其统计学意义。学生t检验用于评估定量因素(也称为“ATD”角度),用卡方检验分析定性变量(也称为指纹图谱)。0.05或更小的P值被认为是显著的。
■在这项研究中,与对照组相比,男性(P0.001)和女性(P0.001)的手掌角度“ATD”减小,这在统计学上是非常显著的。在我们的研究中,我们发现,与男性对照相比,男性病例中的螺纹和牙弓数量较低,差异有统计学意义(P=0.020和P=0.010)。男性病例比男性对照组有更多的环,统计学上显著更大(P<0.001)。
■在这项最新研究中,发现无烟烟草使用者与手掌皮纹之间存在关联.虽然皮纹学无法识别滥用酒精和/或香烟包装的人,这项研究的结果可能有助于进一步制定诊断指南.
