    Overall survival from the date of surgical intervention. A, Survival for all patients as a single group: correlation between survival and preoperative delay as a continuous variable was not significant (P = .54; hazard ratio of 1.06 and 95% CI of 0.87-1.30 for a 90-day increment in delay). B, Survival for patients grouped by duration of preoperative delay (solid line, <90 days; dashed line, >90 days): difference by log rank was not significant (P = .78).
