¹This table analyzes the association between each baseline indicator and depression in acute intracerebral hemorrhage survivors by univariate logistic regression. Continuous variables (e.g., albumin) and categorical variables (e.g., hematoma location) were included as independent variables, with “presence of depression” as the dependent variable. For categorical variables, “lobe” (hematoma location) and “0 points” (brain atrophy grade) served as reference groups. The results identified 8 indicators with statistical differences (P < 0.05) for subsequent multivariate analysis.

OR: Odds ratio; CI: Confidence interval.
