概括

一项关于代谢功能障碍相关的脂肪性肝病 (MASLD) 的新研究发现,虽然之前的亚型模型具有有限的概括性,但心脏代谢和肝脏特异性模式始终出现风险分层.

科学领域:

心脏病学心脏病学
肝病学肝病学是一种肝病学.
流行病学流行病学

背景情况:

与代谢功能障碍相关的脂肪性肝病 (MASLD) 呈现出显著的异质性,使风险分层复杂化.
以前的集群模型确定了肝脏特异性和心脏代谢亚型,但在更广泛的人群中缺乏验证.

研究的目的:

为MASLD亚型验证和复制先前的集群模型.
评估这些亚型对死亡风险的预后相关性.

主要方法:

利用了3300名MASLD参与者在国家健康和营养检查调查 (NHANES III) 中的数据.
用于集群导出和Cox比例危险模型进行死亡风险分析.
经过验证和复制的子类型分配以评估可通用性.

主要成果:

集群分配在验证和复制之间显示出有限的可重现性,但整体模式仍然存在.
确定了广泛的心脏代谢和肝脏特异性亚型.
心脏代谢与持续较高的死亡风险有关,而肝脏特异性没有显著的关联.

结论:

马斯尔德分类模型的概括性有限.
对心脏代谢和肝脏特异性模式的一致识别表明,对风险分层有潜在的有用性,需要进一步验证.

Cluster Sampling Method

Cluster Sampling Method

Appropriate sampling methods ensure that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
To choose a cluster sample, divide the population into clusters (groups) and then randomly select some of the clusters. All the members from these clusters are in the cluster sample. For example, if you randomly sample four departments from your...
