Resumen
La revisión editorial por pares es ampliamente utilizada, pero carece de pruebas sólidas de su efectividad. Los estudios muestran resultados mixtos sobre su impacto en la calidad, legibilidad y sesgo, lo que indica que sus efectos siguen siendo inciertos.
Área de la Ciencia:
- Publicaciones biomédicas en el campo de la edición.
- La comunicación científica es la comunicación científica.
Sus antecedentes:
- La revisión editorial por pares es una práctica estándar para las publicaciones de revistas.
- Su presunto beneficio es mejorar la utilidad de la investigación publicada.
Objetivo del estudio:
- Para sintetizar la evidencia sobre los efectos de la revisión por pares editorial en las revistas biomédicas.
- Para evaluar el impacto de varias etapas y métodos de revisión por pares.
Principales métodos:
- Realizó búsquedas exhaustivas en bases de datos y se puso en contacto con organizaciones profesionales.
- Identificó y revisó 19 estudios comparativos con intentos de controlar los factores de confusión.
- No agrupó los resultados debido a la heterogeneidad en el diseño y los resultados del estudio.
Principales resultados:
- La evidencia sobre el cegamiento de los revisores / autores no es concluyente, con algunos estudios que sugieren efectos positivos, pero se enfrentan a limitaciones metodológicas.
- Las listas de verificación mostraron resultados mixtos en la mejora de la calidad de los informes.
- Los árbitros de capacitación no mejoraron consistentemente el rendimiento, y los métodos de comunicación no tuvieron un efecto demostrable en la calidad.
- Algunos estudios indicaron que la revisión por pares mejora la legibilidad y la calidad de los informes, pero la generalización es limitada.
Conclusiones:
- La revisión editorial por pares es un proceso ampliamente adoptado pero en gran medida no probado.
- Los efectos reales de la revisión por pares editorial en las publicaciones científicas son inciertos.

The Scientific Method
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...
Feedback Inhibition
Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!
Proofreading
Synthesis of new DNA molecules starts when DNA polymerase links nucleotides together in a sequence that is complementary to the template DNA strand. DNA polymerase has a higher affinity for the correct base to ensure fidelity in DNA replication. The DNA polymerase furthermore proofreads during replication, using an exonuclease domain that cuts off incorrect nucleotides from the nascent DNA strand.Errors during Replication Are Corrected by the DNA Polymerase EnzymeGenomic DNA is synthesized in...
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...
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...

Systematic Error: Methodological and Sampling Errors
In the case of systematic errors, the sources can be identified, and the errors can be subsequently minimized by addressing these sources. According to the source, systematic errors can be divided into sampling, instrumental, methodological, and personal errors.
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...
