- 遗传学 是一个遗传学.
背景情况:
- 甲状腺恶性瘤是一个重大的全球健康问题,特别影响女性.
- 性激素和甲状腺癌发展之间的确切关系尚未完全理解.
- 性激素在甲状腺功能中起着至关重要的作用,需要进一步研究它们在甲状腺恶性瘤中的潜在作用.
研究的目的:
- 调查循环性类固醇水平与甲状腺恶性瘤风险之间的潜在因果关系.
- 利用两个样本的门德尔随机化方法来评估性激素和甲状腺癌之间的遗传相关性.
- 澄清性激素在甲状腺癌易感性中的作用.
主要方法:
- 采用两个样本的门德尔随机化 (MR) 方法,使用遗传变异作为工具变量.
- 利用了针对甲状腺恶性瘤,丸激素,性激素结合环球蛋白 (SHBG) 和雌激素的大型全基因组关联研究数据.
- 进行了MR分析,包括逆方差加权 (IVW),MR-Egger回归和加权中位数方法,以及对质和异质性的敏感性分析. 多变量MR (MVMR) 用于调整甲状腺刺激激素 (TSH).
主要成果:
- 在基因预测的,SHBG或雌激素水平与甲状腺恶性瘤风险之间没有发现显著的因果关系.
- 灵敏度分析没有检测出显著的水平质.

Sex-linked Disorders
109.2K
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

The Thyroid Gland
7.8K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Relative Risk
2.2K
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

Random Error
9.8K
Random or indeterminate errors originate from various uncontrollable variables, such as variations in environmental conditions, instrument imperfections, or the inherent variability of the phenomena being measured. Usually, these errors cannot be predicted, estimated, or characterized because their direction and magnitude often vary in magnitude and direction even during consecutive measurements. As a result, they are difficult to eliminate. However, the aggregate effect of these errors can be...

Random Variables
17.9K
A random variable is a single numerical value that indicates the outcome of a procedure. The concept of random variables is fundamental to the probability theory and was introduced by a Russian mathematician, Pafnuty Chebyshev, in the mid-nineteenth century.
Uppercase letters such as X or Y denote a random variable. Lowercase letters like x or y denote the value of a random variable. If X is a random variable, then X is written in words, and x is given as a number.
For example, let X = the...

Randomized Experiments
9.1K
The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.
