Figure 1 A heatmap illustrating the correlation between different variables. Correlation coefficients (r) are color-coded: Red indicates positive correlation, blue indicates negative correlation, darker shades represent stronger relationships, with a central axis anchored at r = 0. The map helps visualize patterns of co-variation and potential latent associations among psychological, clinical, and quality of life domains in patients with low anterior resection syndrome. All correlations were computed using the Pearson method. BMI: Body mass index; LARS: Low anterior resection syndrome; QoL: Quality of life.
