2. Figure 1
Overview of the calculation of the transfer score (TS) metric using the “x1” and “x2” weighting factors to compute a weighted sum of the proportion of patients managed at a non-trauma center (non-TC) and the proportion of patients managed at TC. The overall TS metric was normalized on a 0 to 1 scale using the normalization values “a” and “b.” The TS metrics closer to 1 indicate more highly transferred injuries. MVC, motor vehicle crash.

3. Figure 2
Box-and-whisker plots showing median and interquartile ranges (IQRs) for (A) transfer score (TS) and (B) median co-injury adjusted transfer score to account for maximum Abbreviated Injury Scale (TSMAIS) within each age group. The white line in the center of the box represents the median of each age-specific TS and TSMAIS. The upper and lower limits of the boxes show the 25% and 75% quantiles of the TS and TSMAIS within each age group. The lower limit of each line (whisker) represents the value at the 25th% − 1.5 × IQR and the upper limit of each line represents the value at the 75th% + 1.5 × IQR. The n values denote the number of children included in each calculation.

4. Figure 3
Median co-injury adjusted transfer score to account for maximum Abbreviated Injury Scale (TSMAIS) by age and body region. The symbol corresponds to the median TSMAIS of the age group. The lines are drawn to allow the reader to better visualize the trends. The n values denote the number of children included in each calculation.
