Fig. 6. Kaplan-Meier survival curve showing overall survival of patients with and without delayed diagnosis.
Overall survival of patients with delayed diagnosis was shorter than that of patients with timely diagnosis, if initial patients who died due to immediate post-operative complication (< 7 days) were excluded (mean survival, 22.5 ± 2.6 vs. 122.0 ± 29.1 months, p = 0.038).
