	Overall	RP	BT	EBRT
No. pts	1,153	840	209	104
Mean ± SD folate (mcg):^*
Total	709 ± 326	714 ± 321	693 ± 331	702 ± 354
Dietary	442 ± 177	444 ± 179	432 ± 173	448 ± 174
DFE	1,058 ± 578	1,067 ± 569	1,033 ± 596	1,039 ± 625

Total folate includes supplements and fortified foods, dietary folate does not include supplements and DFE of food equals amount contributed by folate naturally plus 1.7 times amount of added folic acid so that DFE can be greater than total folate.
