Chronic Schizophrenia Patient Data on Inflammation, Insulin Resistance, and Symptoms

Supplementary file 1 from a study by Yinghan Tian, last updated April 2026, contains data on 324 patients with chronic schizophrenia and 150 healthy controls. The dataset includes hematological parameters for calculating the TyG and CTI indices, alongside psychiatric symptom scores from the PANSS and CDSS scales. The study was conducted across three hospitals in Anhui Province, China.

Use Cases

• Analyze associations between the TyG index and brain-derived neurotrophic factor (BDNF) levels based on collected hematological parameters.
• Investigate relationships between the C-reactive protein-triglyceride-glucose index (CTI) and depressive symptom scores based on the Calgary Depression Scale for Schizophrenia (CDSS).
• Compare insulin resistance and inflammation indicator levels between patient and control groups based on the study's cross-sectional design.
• Model the correlation between biomarker indices and negative symptom severity based on Positive and Negative Syndrome Scale (PANSS) factor scores.

Strengths

• Includes data from 324 patients with chronic schizophrenia and 150 healthy controls, providing a comparison group.
• Links specific clinical biomarkers (TyG index, CTI) to standardized psychiatric assessment scores (PANSS, CDSS).
• Released under a permissive CC-BY-4.0 license, allowing for reuse and redistribution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 26.5 KB, indicating limited scope.
