Study on the correlation between serum total cholesterol levels and suicidal ideation in patients with first-episode drug-naïve schizophrenia: a cross-sectional study

The higher the serum TC levels, positive symptom factor scores, and depressive symptom factor scores in FEDN SZ patients, the greater the risk of SI. Therefore, timely measurement of serum TC levels during the initial diagnosis of FEND SZ patients can help promptly initiate therapeutic interventions, reduce the incidence of SI, and improve the prognosis of FEND SZ patients.
