TABLE 5.

One-Way ANOVA for Effect of Number of Substances in Prenatal Exposure on CGM, TOT, and HC

Parameter	No. of Substances in Prenatal Exposure					Global P
	0 (n = 13)	1 (n = 7)	2 (n = 3)	3 (n = 7)	4 (n = 5)
TOT, mL	1287	1292 (.91)	1131 (.02)	1194 (.06)	1129 (.006)	.01
CGM volume, mL	853	827 (.42)	772 (.06)	788 (.04)	731 (.002)	.01
HC, cm	55.7	54.9 (.46)	54.5 (.41)	53.6 (.05)	52.3 (.008)	.07

All P values are 2-tailed. Numbers in parentheses are P values for difference between exposure group and group with no prenatal substance exposure; prenatal exposures are cocaine, cigarettes, alcohol, and marijuana. ANOVA indicates analysis of variance.
