Subgroups of CRISP3 expression may correlate with disease-free survival. Performing classification regression tree analysis on CRISP3 expression, three subgroups were found to correlate differently with disease-free survival (a). The three subgroups were merged into two groups, with high or low CRISP3 expression. Subsequent Kaplan–Meier curves were drawn, plotting disease-free survival (b) and recurrence-free survival (c). Black line: low CRISP3 expression; gray line: high expression.
