Glycemic indicators influence hypercoagulability via multisystem pathways in psychiatric inpatients: Structural equation modeling

Figure 2 Flow diagram of patient selection. This study reviewed the electronic medical records of patients admitted to Hangzhou Seventh People’s Hospital between January 2018 and June 2025. Patients with complete data on all three glycemic indicators - fasting plasma glucose, fructosamine, and glycated hemoglobin - were initially identified. Records with diagnoses other than schizophrenia, bipolar disorder, or major depressive disorder were excluded. To ensure independent observations and data quality, duplicate hospitalization records, admissions with an excessively long length of stay (> 100 days), and records containing implausible or erroneous extreme values were further excluded. The final analytical cohort consisted of 4976 patients. FA: Fructosamine; FPG: Fasting plasma glucose; HbA1c: Glycated hemoglobin.
