概括
大多数系统性审查 (SR) 没有报告与主要研究作者联系以求澄清,尽管联系时的响应率为50%. 需要进一步的研究来改善SR中的这一关键方法元素.
科学领域:
- 医学研究方法
- 基于证据的医学
背景情况:
- 系统性审查对基于证据的医学至关重要,它综合了随机对照试验 (RCT) 的数据.
- 在包含的研究中,SR经常面临不完整或不清楚的数据的挑战,需要与作者联系以获得澄清.
- 目前与主要研究作者联系的做法和响应率尚不清楚.
研究的目的:
- 确定SR中的作者联系频率,以澄清数据和偏差风险.
- 确定影响SR作者与主要研究作者联系或不联系的因素.
- 评估SR团队与主要研究作者之间的沟通内容和响应率.
主要方法:
- 在2024年1月1日至2月19日期间发布的RCT的SR系统搜索.
- 由两名审稿人进行独立选和数据提取,高级作者解决冲突.
- 联系了包括SR的作者,以收集他们与主要研究作者的沟通实践的信息.
主要成果:
- 只有38%的受访者明确表示联系了主要研究作者.
- 与急救团队的直接接触试验产生了19.4%的响应率.
- 在没有报告接触的SR中,50%的受访者证实他们已经联系了主要作者.
- 联系障碍包括资源,时间,以前的负面经历,以及被认为低响应的可能性.
结论:
- 大多数在2024年初发布的SR没有向主要研究作者寻求澄清.
- 主要作者报告了50%的响应率.
- 建议进行进一步的研究,以了解反应率,并开发方法来加强RS的作者接触.

01:32The Scientific Method
244.2K
The scientific method is a detailed, empirical problem-solving process used by biologists and other scientists. This iterative approach involves formulating a question based on observation, developing a testable potential explanation for the observation (called a hypothesis), making and testing predictions based on the hypothesis, and using the findings to create new hypotheses and predictions.
Generally, predictions are tested using carefully-designed experiments. Based on the outcome of these...

45.0K
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.

01:27Correlation and Causation
39.5K
Statistical tests can calculate whether there is a relationship, or correlation, between independent and dependent variables. An indirect relationship of the variables signifies a correlation, while a direct relationship shows causation. If it is determined that no connection exists between the variables, then the correlation is a coincidence.
Correlation versus Causation
If the dependent variable increases or decreases when the independent variable increases, there is a positive or negative...

7.8K
Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction.
