TABLE 4.

The estimated marginal means and standard errors of NIPTS₃₄₆ difference between the actual measured NIPTS₃₄₆ and the ISO 1999 predicted NIPTS₃₄₆ for BAA and kurtosis by BAA groups

Effect	Group	Estimated Mean	Standard Error	95% Confidence Interval
				Lower Bound	Upper Bound
BAA*	Unadjusted (UA)	6.77	0.26	6.27	7.27
	KA	0.03	0.26	−0.47	0.53
Kurtosis×BAA†	K1×KA	1.23	0.51	0.23	2.23
	K1×UA	3.72	0.51	2.73	4.72
	K2×KA	0.08	0.29	−0.50	0.66
	K2×UA	6.35	0.29	5.77	6.92
	K3×KA	−0.96	0.49	−1.93	0
	K3×UA	10.24	0.49	9.27	11.21

BAA, before-and-after-adjustment; KA, Kurtosis-adjusted.

^*p value for NIPTS₃₄₆ difference between KA and UA is <0.001.

^†p values for NIPTS₃₄₆ difference between (K_i×KA) and (K_i×UA) pairs (i = 1, 2, and 3) are <0.001.
