Table 5. Global Moran's I of nine GIS-based measures in access to mammography in St. Louis.

Variable	Moran's I (95% CI)
DST	0.42 (0.41–0.42)
DST5	0.48 (0.47–0.49)
DES	0.12 (0.11–0.13)
SAU	0.71 (0.71–0.72)
SAC	0.47 (0.46–0.47)
SA3Q	0.43 (0.43–0.44)
SA3S	0.45 (0.44–0.45)
SA6Q	0.44 (0.43–0.45)
SA6S	0.50 (0.49–0.51)

(DST: shortest travel time; DST5: average of 5 shortest travel time; DES: density; SAU: spatial accessibility index from the model without weighting parameter; SAC: spatial accessibility index from the model with continuous weighting parameter; SA3Q: spatial accessibility index from the zonal weighted model with 3 time zones and quick decay weighting; SA3S: spatial accessibility index from the zonal weighted model with 3 time zones and slow decay weighting; SA6Q: spatial accessibility index from the zonal weighted model with 6 time zones and quick decay weighting; SA6S: spatial accessibility index from the zonal weighted model with 6 time zones and slow decay weighting.)
