Transportation as a barrier to colorectal cancer care

Table 2 Predicted Probabilities of Reporting Transportation Barriers

Distance to the VA	Chaotic Lifestyle	Predicted Probability (95% CL)
≤ 20 miles	Less chaotic lifestyle (score < 16)	0.102 (0.036, 0.258)
≤ 20 miles	More chaotic lifestyle (score ≥ 16)	0.184 (0.063, 0.431)
> 20 miles	Less chaotic lifestyle (score < 16)	0.158 (0.080, 0.291)
> 20 miles	More chaotic lifestyle (score ≥ 16)	0.272 (0.159, 0.425)

^aWe used PROC LOGISTIC in SAS to estimate the predicted probability of transportation barriers for Veterans who (1) traveled ≤20 miles to the VA and had a less chaotic lifestyle, (2) traveled ≤20 miles to the VA and had a more chaotic lifestyle, (3) traveled > 20 miles to the VA and had a less chaotic lifestyle, and (4) traveled > 20 miles to the VA and had a more chaotic lifestyle (the reference group is Veterans who reported no difficulties with transportation to or from cancer care appointments). Predicted probabilities were not statistically significant for all groups
^bWe tested goodness of fit with deviance and Pearson chi square tests, which indicated reasonable model fit
