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

Figure 5 Pathways linking fasting plasma glucose to D-dimer across four upstream pathways. A: Lipid pathway; B: Blood pressure pathway; C: Inflammation pathway; D: Nutrition pathway. A-D present system-specific path diagrams illustrating how fasting plasma glucose relates to D-dimer through upstream physiological pathway indices and a downstream coagulation substrate node. Each panel displays the full set of modeled pathways within the corresponding domain, including the direct association fasting plasma glucose → D-dimer and the indirect pathway fasting plasma glucose → upstream pathway index → coagulation (substrate) → D-dimer. Direct paths from each upstream pathway index to D-dimer are also shown, where specified. Panels correspond to four upstream pathway domains: (A) Lipid metabolism; (B) Blood pressure; (C) Inflammation; and (D) Nutrition. Arrow color denotes the direction of the standardized association (red = positive; cyan = negative), arrow thickness reflects the magnitude of the standardized coefficient (|Std.β|; 0-0.1, 0.1-0.3, > 0.3), and line type indicates statistical significance (solid = significant; dashed = not significant). FPG: Fasting plasma glucose; BP: Blood pressure.
