Association Analysis of Participants: Dermatitis Rash and Platelet Levels from CHNS

A dataset of 7,337 participants from the China Health and Nutrition Survey (CHNS), including 172 Dermatitis Rash (DR) cases and 7,165 controls. It was created by Yue Jiang to analyze the association between serum platelet (PLT) levels and DR risk using multifactor regression and restricted cubic splines. The dataset was last updated on 2026-05-04.

Use Cases

• Assessing the relationship between platelet levels and dermatitis rash risk based on the reported odds ratios.
• Investigating the moderating effect of sex on the PLT-DR association as mentioned in the description.
• Exploring nonlinear associations between biomarkers and disease risk using restricted cubic spline models.
• Evaluating the impact of covariates like smoking history and residency on dermatitis rash.

Strengths

• Includes data from 7,337 participants, providing a substantial sample size for analysis.
• Contains 172 confirmed Dermatitis Rash cases, enabling case-control comparisons.
• Analysis results, including specific odds ratios and p-values, are documented in the description.

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The dataset is very small (5.5 KB), indicating limited scope or a summary of results rather than raw participant data.
• Data may reflect geographic and demographic biases inherent to the China Health and Nutrition Survey source.
