Table 3 Distribution of primary green space exposures in the analytic sample (n = 943)

Exposure	Mean	(SD)	Min	25th p.	Median	75th p.	Max
NDVI in 300 m buffer^a	0.592	(0.08)	0.249	0.543	0.596	0.647	0.789
Tree Cover (%) ^b	37.6	(12.0)	4.4	29.1	37.3	45.7	80.7
Park proximity (m) ^c	795	(862)	3	282	549	987	8417
