Association of fibrosis-4 (FIB-4) index with odds ratios of post-stroke depression (PSD) at 3 months. The restricted cubic spline of odds ratios and 95% confidence intervals with 4 knots located at the 5th, 35th, 65th, and 95th percentiles of the distribution of the FIB-4 score. The midpoints of FIB-4 score reference groups from categorical analyses serve as the reference point. Odds ratios were controlled for the same covariates included in model 2 in Table 3
