Survival analysis in early stage colorectal cancer. Survival in early stage CRC for diagnostic delay longer and shorter than the median delay of 23.5 weeks. On the Y-axis the proportion of patients surviving is plotted. On the X-axis the time is plotted in weeks. Log-rank p = 0.93 using Kaplan-Meier analysis. In the Cox regression model with survival as dependent variable and median delay, age, open access endoscopy, number and type of symptoms as independent variables, the odd's ratio for survival in patients with long delay (>median) versus short delay (≤median) was 1.1 (95% confidence interval 0.5 to 2.6; p = 0.76). Blue line: delay < median delay. Green line: delay > median delay
