Resumen
Google Scholar y Scopus proporcionan un mayor recuento de citas que Web of Science para artículos médicos. Estas bases de datos también difieren cualitativamente en los tipos de artículos que citan, lo que afecta el análisis de citas.
Área de la Ciencia:
- La bibliometría y la bibliometría.
- La informática médica es la informática médica.
- Publicaciones Científicas Editorial Científica.
Sus antecedentes:
- Web of Science fue la base de datos de seguimiento de citas primaria.
- Las bases de datos emergentes como Scopus y Google Scholar ofrecen un seguimiento de citas alternativo.
- El rendimiento comparativo de estas bases de datos de citas sigue sin establecerse.
Objetivo del estudio:
- Para comparar los perfiles de recuento de citas a través de Web of Science, Scopus y Google Scholar.
- Para analizar las diferencias cuantitativas y cualitativas en los datos de citas.
- Para evaluar el rendimiento de la base de datos para artículos en revistas médicas generales.
Principales métodos:
- Un estudio de cohorte de 328 artículos publicados en las revistas JAMA, Lancet y NEJM (1999-2000).
- Los recuentos de citas se extrajeron hasta junio de 2008 de Web of Science, Scopus y Google Scholar.
- Los modelos de regresión lineal analizaron la interacción de las características del artículo con las bases de datos.
Principales resultados:
- Google Scholar (mediana de 160) y Scopus (mediana de 149) obtuvieron más citas que Web of Science (mediana de 122).
- Scopus capturó más citas no en inglés y de revisión, y menos citas de artículos / editoriales / cartas en comparación con Web of Science.
- Google Scholar mostró menos citas para estudios financiados por la industria, estudios de drogas / dispositivos y artículos escritos por grupos en comparación con Web of Science.
Conclusiones:
- Web of Science, Scopus y Google Scholar ofrecen distintos recuentos de citas cuantitativas y cualitativas.
- La elección de la base de datos afecta las métricas de citación y el análisis bibliométrico.

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

28.9K
The chi-square test is a statistical hypothesis test. It is used to check whether there is a significant difference between an expected value and an observed value. In the context of genetics, it enables us to either accept or reject a hypothesis, based on how much the observed values deviate from the expected values.
The chi-square test was developed by Pearson in 1990.
The first step of performing a Chi-square analysis is to establish a null hypothesis, which assumes that there is no real...

At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is...

4.7K
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...
