Geographic locations illustrated in figure 1. a Short or long survival areas detected by the spatial scan statistic are illustrated in Figure 1. b Averages for each area are based on the census tract values assigned to the cases. c Directly adjusted 5 year colorectal cancer specific survival rates are based on a Cox regression model adjusted for specified covariates. The method adjusts survival time by covariates to adjust for any imbalance of CRC case characteristics inside and outside defined survival area (e.g All CRC cases inside area A versus all CRC cases outside area A). d Inside refers to the adjusted survival time of all CRC cases inside the specified survival area (e.g Cases inside detected area A). Outside refers to the adjusted survival time of all CRC cases outside the specified survival area (e.g. Cases outside detected area A). P-value from spatial scan statistic Monte Carlo permutation test. |
