BMC Pediatrics

Table 10 Summary results for the four autism assessment tools, for the Arizona and National groups combined.

	Placebo-Pre	Placebo-Post	Difference	Supplement- Pre	Supplement Post	Difference	P-Value
PGI-R (Average Change)			+0.34 +/- 0.54			+0.67 +/- 0.65	0.008
ATEC (Total)	59 +/- 28	50 +/- 27	-9.6	63 +/- 22	51 +/- 20	-11.9	n.s.
SAS	5.2 +/- 2.6	5.2 +/- 2.6	0.0	5.4 +/- 2.0	5.1 +/- 2.2	-0.3	n.s.
PDD-BI (Autism Composite)	-66 +/- 64	-79 +/- 68	-13.4	-62 +/- 51	-78 +/- 52	-16.4	n.s.

Note that the ATEC, SAS and PDD-BI are assessed at the beginning and end of the study, whereas the PGI-R is only assessed at the end, as it only evaluates the changes observed. Only the PGI-R found a significant difference between the supplement and placebo groups, so it is highlighted in a bolder font.
