# Visualization of childhood allergic diseases based on VOSviewer and CiteSpace

## TL;DR

This study maps research trends in childhood allergic diseases from 2014 to 2024, highlighting eczema's growing attention and the lack of research on cough-variant asthma.

## Contribution

A novel bibliometric analysis using VOSviewer and CiteSpace to visualize trends and gaps in childhood allergic disease research.

## Key findings

- Eczema research has grown the most compared to other childhood allergic diseases.
- Cough-variant asthma has significantly fewer studies, with only 110 papers in 10 years.
- Research collaboration and focus have shifted toward topics like microbiome, genetics, and environmental factors.

## Abstract

Childhood allergic diseases, such as eczema, allergic rhinitis, bronchial asthma, and cough-variant asthma, are a growing health concern around the world. There is a lot of research about these diseases, but a clear and complete study is still needed to better understand them and help guide future research.

This study used a bibliometric analysis of research on childhood allergic diseases from 2014 to 2024. The main goal was to find patterns in publications, main researchers, research focuses, teamwork between groups, and new topics. Data were collected from Web of Science, Scopus, and PubMed. The study included English-language articles and reviews only. The tools VOSviewer and CiteSpace were used to study publication patterns, where research was done, which authors and journals worked together, how often papers were cited together, which papers were cited the most, and how keywords appeared and formed groups.

The amount of research was different for each disease. Eczema got the most attention and kept growing. Cough-variant asthma had fewer studies. The United States and China were the main countries that did most of the work and had well-known authors. The focus of studies changed from general studies about disease spread to more detailed topics like the microbiome, genetics, special treatments, environmental causes, other health problems that happen together, and the effects of COVID-19. The way researchers worked together was not the same for all diseases. This showed that research was more developed and better connected for some diseases and less developed for others, mainly for cough-variant asthma.

This study gives a short look at recent research on childhood allergic diseases. It shows that eczema research is growing fast, but cough-variant asthma is still studied much less, with only 110 papers in 10 years. This big difference shows a clear lack of knowledge. These results can help make better research plans and improve medical care in this field.
