Summary
Research on cough, a common symptom of allergic diseases, significantly increased in the 1990s. The United States led in publication volume, while other nations excelled in research quality, indicated by citation impact.
Area of Science:
- Allergy and immunology research
- Respiratory medicine
- Bibliometrics
Background:
- Cough is a significant symptom in allergic diseases, posing a considerable health burden.
- Limited information exists regarding the current research landscape of cough.
Purpose of the Study:
- To conduct a scientometric analysis of long-term trends in cough research.
- To identify recent developments and patterns in the scientific literature on cough.
Main Methods:
- A comprehensive search of cough-related publications from 1900 to 2007 was performed using Web of Science databases.
- Scientometric methods and density-equalizing calculations were employed to analyze publication data.
- International collaboration patterns were assessed using radar charts.
Main Results:
- A total of 12,960 cough-related publications from 132 countries were identified.
- The United States of America (USA) was the most productive country, followed by the United Kingdom (UK).
- International co-authorship increased significantly from the early 1990s, with the USA and UK playing leading roles.
Conclusions:
- Cough research experienced a notable surge in activity starting in the 1990s.
- While the USA dominated publication output, other countries demonstrated higher research quality based on citation impact.

01:25Statistical Methods for Analyzing Epidemiological Data
Epidemiological data primarily involves information on specific populations' occurrence, distribution, and determinants of health and diseases. This data is crucial for understanding disease patterns and impacts, aiding public health decision-making and disease prevention strategies. The analysis of epidemiological data employs various statistical methods to interpret health-related data effectively. Here are some commonly used methods:
01:21Causality in Epidemiology
Causality or causation is a fundamental concept in epidemiology, vital for understanding the relationships between various factors and health outcomes. Despite its importance, there's no single, universally accepted definition of causality within the discipline. Drawing from a systematic review, causality in epidemiology encompasses several definitions, including production, necessary and sufficient, sufficient-component, counterfactual, and probabilistic models. Each has its strengths and...
01:22Respiratory Volumes and Capacities
The respiratory system is responsible for the intake of oxygen and the expulsion of carbon dioxide from the body. Respiratory volumes describe the volume of air in the lungs at different phases of the respiratory cycle. Tidal volume is the air breathed in and out during normal, quiet breathing. Inspiratory reserve volume is the air that can be forcefully inspired beyond the tidal volume. In contrast, expiratory reserve volume refers to the air that can be expelled from the lungs after a normal...

Pulmonary Function Tests (PFTs)
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
PFTs involve using a spirometer, a...
