1 Figure 1: Diagnostic performance of mortality prediction indices MPI4 (dash-dotted line), MPI5 (dashed line), and MPI6 (continuous line) for identification of mortality in sea turtles (n = 25 dead and 118 live sea turtles). The diagonal (dotted) line indicates the area under the curve = 0.50 (a non-informative test). Arrow shows cut-off value of a score ≥8 for MPI6 with highest sensitivity = 88.0 and specificity = 80.5%.

2 Figure 2: Frequency-distribution of MPI6 mortality prediction index scores in 118 sea turtles that survived and 25 sea turtles that died. The horizontal line across the MPI6 score indicates the cut-off value used to predict mortality (yes/no). Using a cut-off value ≥8, the calculated sensitivity = 88% and the specificity = 80.5%.
