- 遗传学 是一个遗传学.
- 在瘤学瘤学.
- 公共卫生 公共卫生
背景情况:
- 多基因风险评分 (PRS) 对前列腺癌风险分层有希望.
- 人口,生活方式和社会经济因素对PRS实用性的影响尚不清楚.
研究的目的:
- 为了验证一个多祖先的前列腺癌PRS.
- 评估人口,生活方式和医疗保健准入因素如何改变PRS的有效性.
主要方法:
- 通过我们所有人研究计划 (7577例前列腺癌病例,90608例对照) 的数据验证了451种多种祖先的PRS.
- 进行了祖先分层,年龄分层和多变量分析,以评估取决于上下文的影响.
- 进行了一项全现象关联研究 (PheWAS),以确定与PRS相关的临床结果.

Polygenic Traits
69.1K
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...

Reliability and Validity
14.1K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Self Within Cultural Contexts
240
Cultural frameworks for understanding the self are often categorized into two broad orientations: individualism and collectivism. These paradigms influence how people define themselves, relate to others, and interpret their social worlds. Each orientation offers distinct perspectives on autonomy, responsibility, and the role of the individual within a community.Individualistic CulturesIn individualistic cultures like North America and Western Europe, identity is understood as autonomous and...

Introduction to z Scores
11.2K
A z score (or standardized value) is measured in units of the standard deviation. It tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a zero z score. It is important to note that the mean of the z scores is zero, and the standard deviation is one.

z Scores and Area Under the Curve

z scores are the standardized values obtained after converting a normal distribution into a standard normal distribution. A z score is measured in units of the standard deviation. The z score tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a z score of...
