Fig 1 Relationships between the work relative value weight (RVU) (A) or the practice expense relative value weight (RVU) (B) for each procedure and the median length of stay for that procedure. A listing of the procedure represented by abbreviations is given in Table 3. The symbol rs represents the Spearman correlation coefficient for the association, with its associated p value.

Fig 2 Relationships between the work relative value weight (RVU) (A) or the practice expense relative value weight (RVU) (B) for each procedure and the median total hospital charges for that procedure. A listing of the procedure represented by abbreviations is given in Table 3. The symbol rs represents the Spearman correlation coefficient for the association, with its associated p value.

Fig 3 Relationships between the work relative value weight (RVU) (A) or the practice expense relative value weight (RVU) (B) for each procedure and the percentage of patients who died during the hospitalization for that procedure. A listing of the procedure represented by abbreviations is given in Table 3. The symbol rs represents the Spearman correlation coefficient for the association, with its associated p value.
