Longitudinal Research

11.7K
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...

Data Collection by Observations

11.0K
Data collection refers to a systematic way of obtaining, observing, measuring, and analyzing accurate information. Observational studies are one of the most widely used methods of data collection. It involves collecting data by observing the behavior and physical characteristics of a sample without making any modifications to the sample.
An astronomer viewing the motion and brightness of stars in the sky and recording the data is an example of observational data collection. A botanist recording...

Observational Studies

8.9K
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...

Study Designs in Epidemiology

1.7K
Epidemiological study designs are fundamental tools for investigating the distribution, determinants, and control of health conditions in populations. They help researchers understand the relationships between exposures and outcomes, and they broadly fall into two categories: "observational" and "experimental" studies.
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and...

  • 宫病理学 宫病理学

背景情况:

  • 评估内宫切除 (ECC) 与转化区大循环切除 (LLETZ) 的实用性.
  • 评估ECC用于检测LLETZ边缘以上的癌前病变的诊断价值.
  • 在这种情况下,解决关于ECC预测价值和准确性的有限数据.

研究的目的:

  • 为了确定LLETZ后从ECC进行的组织学发现的分布.
  • 评估ECC提供的额外诊断信息.
  • 评估ECC结果对后续临床治疗决策的影响.

主要方法:

  • 在2009-2021年期间,对1121名接受LLETZ和ECC治疗的患者进行了回顾性队列研究.
  • 分析主要结果参数:组织学诊断和样本充分性.
  • 评估ECC对治疗方法和残留疾病检测的影响.

主要成果:

  • 在只有1.7%的病例中,ECC提供了额外的诊断信息.
  • 在0.2%的患者中,ECC结果影响了随后的治疗.
  • 负的ECC显示了残留疾病检测的低负预测值 (43.8%).

结论:

  • 在LLETZ时代的常规ECC性能是可疑的.
  • 目前的指导方针有利于在LLETZ后进行HPV测试,以评估治疗成功.
  • 增加了ECC的诊断产量并不总是证明其常规使用是合理的.
