(A) Heatmap illustrating correlations between biochemical markers in patient and control groups. Positive correlations appear in red, negative in blue, with intensity indicating correlation strength. The diagonal represents perfect self-correlation (coefficient = 1), aiding in identifying biomarker relationships relevant to disease mechanisms and prognosis. (B) Heatmap showing biochemical marker relationships in remission and non-remission groups. Red indicates positive correlations, blue indicates negative, with the diagonal representing self-correlation.
