Influencing factors and construction of a nomogram for post-stroke depression in patients with chronic stroke

Figure 1 Blood biochemical parameters in the two patient groups. A: Mean platelet volume comparison; B: Lymphocyte levels between groups; C: Monocyte counts in both cohorts; D: Neutrophil measurements across groups; E: Neutrophil-to-lymphocyte ratio analysis; F: Platelet-to-lymphocyte ratio evaluation; G: Lymphocyte-to-monocyte ratio assessment. ^aP < 0.001 vs the non-post-stroke depression group. MPV: Mean platelet volume; NLR: Neutrophil-to-lymphocyte ratio; PLR: Platelet-to-lymphocyte ratio; LMR: Lymphocyte-to-monocyte ratio.

Figure 2 Nomogram visualization of the post-stroke depression risk-prediction model and performance validation. A: Risk prediction nomogram for post-stroke depression; B: Internal validation with 1000 bootstrap replicates; C: Calibration curve evaluation. Severity means severity of neurological impairment. PSD: Post-stroke depression; NLR: Neutrophil-to-lymphocyte ratio; PLR: Platelet-to-lymphocyte ratio.
