概括
受访者驱动采样 (RDS) 对于招募胃癌 (GC) 患者进行病例控制研究是不可行的,因为参与率和转诊率很低. 这凸显了吸引高风险少数群体参与癌症研究所面临的挑战.
科学领域:
- 在瘤学瘤学.
- 公共卫生 公共卫生
- 流行病学 流行病学
背景情况:
- 胃癌 (GC) 不成比例地影响美国的少数民族,包括亚洲人和太平洋岛民.
- 有效的治疗需要高风险少数群体参与研究,但招聘面临语言,访问,恐惧和不信任等障碍.
- 受访者驱动抽样 (RDS) 是一种通过社交网络招募代表性不足的人群的策略,尽管其在病例控制研究中的使用是未经记录的.
研究的目的:
- 检查使用RDS用于招募参与者参加胃癌 (GC) 查器开发研究的可行性.
- 评估RDS在招募大量GC病例和对照对试点研究的有效性.
主要方法:
- 一项试点研究使用了RDS,GC病例作为初始种子来招募对照.
- 目标是通过三个转诊浪潮招募8个GC病例和112个对照.
- 每个案例都被要求引用两个潜在的控制.
主要成果:
- 在联系的27个GC病例中,10个被拒绝,4个不愿意招募控制.
- 在13个被招募的案例中,只有5个完成了调查.
- 在完成调查的5人中,只有3人通过了推券,2人推了3个潜在的对照.
结论:
- 该研究表明,用于招募癌症患者的RDS应用存在重大局限性,特别是对于胃癌 (GC) 病例控制研究.
- 诸如GC患者之间的社交网络受限,激励措施不足或其他未解决的问题等因素可能解释了招聘和转诊成功率低的原因.
- 在类似的研究环境中,RDS可能不是适合这个人群的招聘策略.

Sampling Plans

Sampling is a crucial step in analytical chemistry, allowing researchers to collect representative data from a large population. Common sampling methods include random, judgmental, systematic, stratified, and cluster sampling.
Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...

Comparing the Survival Analysis of Two or More Groups
197
Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and...

Statistical Methods for Analyzing Epidemiological Data
372
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:
