概括
这项门德尔随机化研究发现,外周血液白细胞计数与整体乳腺癌风险之间没有显著的因果关系. 进一步的分析也显示,与特定的乳腺癌亚型没有实质性的相关性.
科学领域:
- 遗传学 遗传学 是一个
- 流行病学 流行病学
- 在瘤学瘤学.
背景情况:
- 周围血液白细胞计数与炎症和免疫反应有关.
- 了解它们在乳腺癌发展中的作用对于预防和治疗策略至关重要.
研究的目的:
- 使用孟德尔随机化 (MR) 调查外周血液白细胞计数和乳腺癌风险之间的潜在因果关系.
- 探索特定白细胞亚型和乳腺癌亚型之间的关联.
主要方法:
- 利用血细胞联盟 (BCX) 的遗传数据来计算白细胞数量,以及乳腺癌协会联盟 (BCAC) 和FinnGen联盟的乳腺癌数据.
- 采用多种MR方法,包括反变量加权 (IVW) 和受约束的最大概率和模型平均值 (cML-MA),并使用MR-Egger和MR-PRESSO进行灵敏度分析.

Randomized Experiments
7.0K
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.

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches
133
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Genome-wide Association Studies-GWAS
13.5K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
