まとめ
この研究では,ポジティブとネガティブな結果を報告した提出された手稿の出版率に有意な差は認められませんでした. 出版バイアスは,以前に考えられていたように,原稿の提出後にそれほど一般的ではないかもしれません.
科学分野:
- 医学研究の誠実さ
- 学術出版は学術的な出版である.
- バイオ統計学 バイオ統計学
背景:
- ポジティブな結果がネガティブな結果よりも優れている出版バイアスは,科学文献で知られている問題です.
- 著者は,ネガティブな結果を持つ原稿を提出する傾向が少なく,このバイアスに寄与するかもしれません.
- この研究では,原稿がジャーナルに提出された後に出版バイアスが存在するかどうかを調査しています.
研究 の 目的:
- 統制試験の陽性結果を報告する提出された原稿が,否定的な結果を報告する原稿と比較して,出版される可能性が高いかどうかを判断する.
- 提出された原稿の文脈における出版バイアスを評価する.
主な方法:
- 展望的なコホート研究では,1996年2月から1999年8月にかけてJAMAに提出された745本の原稿を分析した.
- 手稿は,報告された結果に基づいて分類されました: 陽性 (P<0.05 プライマリアウトカム),ネガティブ,または不明確.
- 研究の特徴と品質指標を評価し,潜在的な混同要因を調整しました.
主要な成果:
- 提出された745件の原稿のうち,133件 (17.9%) が出版されました.
- 公開率は,ポジティブな結果は20.4%,ネガティブな結果は15.0%,不明な結果は19.0%でした.
- 試験の特徴と質を調整した後,陽性結果と陰性結果の公表の確率比は1.30 (95%CI,0.87-1.96) であり,統計的に有意ではありませんでした.
結論:
- この研究では,提出された原稿の出版バイアスの統計的に有意な証拠は見つかりませんでした.
- ポジティブな結果を報告した提出された原稿は,ネガティブな結果を報告した原稿よりも著しく高い割合で出版されなかった.
- これは,出版バイアスが,手稿がジャーナル提出プロセスに入ると,重要な要因ではないかもしれないことを示唆しています.

Types of Selection
Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...
Reason and Intuition
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the brain can only use...
Groupthink
When in group settings, we are often influenced by the thoughts, feelings, and behaviors around us. Groupthink is another phenomenon of conformity where modification of the opinions of members in a group aligns with what they believe is the group consensus (Janis, 1972). In such situations, the group often takes action that individuals would not perform outside the group setting because groups make more extreme decisions than individuals do. Moreover, groupthink can hinder opposing trains of...
Decision Making: P-value Method
The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can have a...

Decision Making: Traditional Method
The process of hypothesis testing based on the traditional method includes calculating the critical value, testing the value of the test statistic using the sample data, and interpreting these values.
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...

Bias
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...
