Figure 3

Scatter plot to assess the association between basic costs and total costs. The scatter plot shows basic costs on the y-axis and total costs on the x-axis. Each data point represents a single patient (n = 469 patients with complete cost data). There is a strong linear relationship between basic costs and total costs (Spearman's rank correlation coefficient, r _s : 0.91). Data points on the dashed 45° indifference line represent patients, where total costs are fully represented by basic costs.
