Overview of Biostatistics in Health Sciences01:19

Overview of Biostatistics in Health Sciences

Biostatistics involves the application of statistical techniques to scientific research in health-related fields, including biology and public health. These techniques are essential for designing studies, collecting data, and analyzing it to draw meaningful conclusions. Given the complexity of biological processes, particularly in studies involving human subjects, biostatistical methods are crucial for effectively organizing and interpreting data that might otherwise obscure underlying patterns...
Biostatistics: Overview01:20

Biostatistics: Overview

Biostatistics plays a crucial role in understanding and analyzing data in healthcare and biology. Biostatisticians conduct experiments, gather evidence, and draw meaningful conclusions using statistical methods and techniques. Different variables form the foundation of biostatistical analysis, allowing researchers to understand and interpret data effectively. These variables are classified into different types, each serving a specific purpose in statistical analysis.
Discrete variables are...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches01:23

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...
Statistical Analysis: Overview01:11

Statistical Analysis: Overview

When we take repeated measurements on the same or replicated samples, we will observe inconsistencies in the magnitude. These inconsistencies are called errors. To categorize and characterize these results and their errors, the researcher can use statistical analysis to determine the quality of the measurements and/or suitability of the methods.
One of the most commonly used statistical quantifiers is the mean, which is the ratio between the sum of the numerical values of all results and the...
Mouse Models of Cancer Study02:43

Mouse Models of Cancer Study

Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

Area of Science:

  • Bibliometrics
  • Research Impact Analysis
  • Publication Science

Background:

  • The National Institutes of Health (NIH) is a primary funder of biomedical research in the United States.
  • Understanding the publication output and impact of NIH-funded research is crucial for evaluating research effectiveness.
  • Grant-to-article linkage data provides a direct method to assess research productivity and influence.

Purpose of the Study:

  • To introduce the availability of grant-to-article linkage data for NIH grants.
  • To analyze publication outputs and citation impacts associated with NIH-funded research.
  • To explore trends in research collaboration and funding effectiveness.

Main Methods:

  • Linked articles to acknowledging NIH grants using PubMed data and the NIH Scientific Publication Information Retrieval & Evaluation System (SPIRES).
  • Incorporated citation data from Scopus for impact analysis.
  • Analyzed a dataset comprising 2,572,576 records from 1980 to 2009.

Main Results:

  • Synergies between NIH institutes are increasing, with 29% of articles acknowledging multiple institutes.
  • The median time lag from grant award to publication is 3 years.
  • Articles acknowledging US Public Health Service (PHS) funding are cited twice as much as unfunded US articles, with dual PHS and non-US funding yielding 40% more citations.

Conclusions:

  • US PHS funding effectively supports research with high citation impact.
  • The developed linkage data enables further in-depth analysis of research performance.
  • NIH funding demonstrably enhances the global impact of scientific publications.
