Impact of post-stroke depression on the prognosis of stroke-associated pneumonia and analysis of predictive factors: A retrospective study of 186 patients

Figure 2 Forest plot of odds ratios (95% confidence interval) for predictive factors of adverse prognosis in stroke-associated pneumonia patients from multivariable logistic regression. Blue markers indicate statistically significant independent predictors (P < 0.05); gray markers indicate non-significant variables. The dashed vertical line represents odds ratio = 1.0 (no effect). OR: Odds ratio; 95%CI: 95% confidence interval; APACHE II: Acute Physiology and Chronic Health Evaluation II; PSD: Post-stroke depression; BDNF: Brain-derived neurotrophic factor; MV: Mechanical ventilation; MDR: Multi-drug resistant; IL-6: Interleukin-6; NIHSS: National Institutes of Health Stroke Scale.
