- 评估SMAC-1试验的基线轮的瘤发现.
- 通过多元组件设计来加强传统的肺癌查计划.
主要方法:
- 通过媒体和全科医生招募高风险受试者 (>55岁,目前/最近吸烟者).
- 参与者接受了LDCT,血液分析 (生物标志物,循环瘤细胞),心血管评估和风险分析.
- 使用Maisonneuve风险再计算模型确定了个性化查间隔.
主要成果:
- 1112名高风险受试者参与,平均年龄为64岁,平均PLCOm2012风险为5.6%.

Longitudinal Research
12.0K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Statistical Methods for Analyzing Epidemiological Data
367
Epidemiological data primarily involves information on specific populations' occurrence, distribution, and determinants of health and diseases. This data is crucial for understanding disease patterns and impacts, aiding public health decision-making and disease prevention strategies. The analysis of epidemiological data employs various statistical methods to interpret health-related data effectively. Here are some commonly used methods:

Observational Studies
8.6K
Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

Crossover Experiments
2.8K
Crossover experiments, also called the repeated-measurements design, is a study design in which all experimental units are exposed to all treatments in different periods. Crossover experiments are generally used in psychology, the pharmaceutical industry, agriculture, and medicine.
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.
