Figure S7 from Evaluating for Correlations between Specific Metabolites in Patients Receiving First-Line or Second-Line Immunotherapy for Metastatic or Recurrent NSCLC: An Exploratory Study Based on Two Cohorts

Correlation heatmap in Cohorts 1 and 2. Correlation analysis of metabolites with significant differences between positive and negative polarity modes. Red indicates a positive correlation, blue indicates a negative correlation, and white indicates a nonsignificant correlation. The depth of color is related to the absolute value of the correlation coefficient, that is, the higher the degree of positive or negative correlation, the darker the color. The point size is related to the significance of the correlation: more significant, smaller p values and larger points.
