まとめ
出版バイアスは,研究レビューに影響します. 非有意義な結果が得られた被動喫煙に関する研究は,有意義な結果が得られた研究よりも長い出版遅延を経験し,科学文献に影響を及ぼしました.
科学分野:
- 環境衛生 環境衛生 環境衛生
- 公衆衛生は公衆衛生である.
- エピデミオロジー エピデミオロジー
背景:
- 出版の遅延や非重要な結果の省略は,科学的レビューに偏見をもたらす可能性があります.
- 出版パターンを理解することは,正確な科学的解釈に不可欠です.
研究 の 目的:
- 被動喫煙の健康への影響に関する未発表の研究の範囲を評価する.
- 統計的に有意な結果を持つ研究と比較して,非有意な結果を持つ被動喫煙研究が公表されるまでに長い時間がかかるか否かを調査する.
主な方法:
- 主な調査員と連絡を取るために,半構造的な電話インタビューアプローチが使用されました.
- 1981年から1995年の間に資金提供された,被動喫煙による健康への影響に関する61件の研究について,情報を収集した.
- 分析のために,公表までの時間と統計的有意性に関するデータを収集した.
主要な成果:
- 61件の研究のうち14件が未発表のままだった.
- 非有意な結果の研究は,有意な結果の研究は3年 (P=.004) であったが,非有意な結果の研究は平均5年 (P=.004) であった.
- 統計的有意性,実験設計,より小さな研究サイズ,および動物被験者が予測された出版時間.
結論:
- 非有意な発見を報告する被動喫煙の研究では,著しい出版遅延が存在します.
- この遅延は,この分野における出版バイアスの可能性を示唆している.
- すべての結果のタイムリーな公表を確保することは,偏見のない科学的理解のために不可欠です.

Breathing
The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...
Lung Capacity
The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.
Gas Exchange and Transport
Gas exchange, the intake of molecular oxygen (O2) from the environment and the outflow of carbon dioxide (CO2) into the environment, is necessary for cellular function. Gas exchange during respiration occurs largely via the movement of gas molecules along pressure gradients. Gas travels from areas of higher partial pressure to areas of lower partial pressure. In mammals, gas exchange occurs in the alveoli of the lungs, which are adjacent to capillaries and share a membrane with them.
Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches
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, controlled...

Stimulants
Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...
