まとめ
生命科学の研究におけるバイアスの報告は低いままです. in vivoの実験報告はin vitroよりも優れているが,重要なジャーナル間の差異は残っている.
科学分野:
- 生命科学
- バイオメディカル 研究
背景:
- 体系的なレビューでは,非臨床生命科学研究におけるバイアスの緩和に関する報告が少ないことが示されています.
- ランダム化,ブラインド化,サンプルサイズ推定などの重要な測定は報告されていない.
研究 の 目的:
- 統計情報に焦点を当てて,非臨床的な記事の最近の報告基準を評価する.
- バイオメディカル研究記事の大量サンプルにおけるバイアス報告の頻度を評価する.
主な方法:
- ジャーナル・シテーション・リポート (Clarivate) からランダムに選択した10のジャーナル.
- 標準化されたチェックリストを使用して2020年に発表された860件の生物医学研究論文の分析.
- 製品の分類 in vivo,in vitro,または組み合わせた方法
主要な成果:
- ランダム化に関する報告率は幅広く変化した (in vivoでは0%,in vitroでは0%,4%).
- ブラインド・コンディションの報告も有意な変化を示した (11% - 71% in vivo, 0% - 86% in vitro).
- In vivo研究では,これらの測定値の報告率は,in vitro研究と比較して一般的に高かった.
結論:
- 偏見の測定値と統計情報の報告基準は最適ではない.
- 報告の質には,in vivoとin vitroの実験論文の間で顕著な違いがある.
- 報告基準の重要なジャーナル間変動が観察されました.

Bias
4.9K
Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...

Bias in Epidemiological Studies
671
Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches
174
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Blind Procedures
12.1K
Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

Ethics in Research
24.0K
Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.

Clinical Trials: Overview
3.4K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...
