IGT net score at three times across groups

	Time 1 A-IGT		Time 2 K-IGT		Time 3 Q-IGT		Effect Size (T1, T2) (Cohen’s d)	N^* for (T1, T2)	Effect Size (T1, T3) (Cohen’s d)	N^* for (T1, T3)
	Mean	SD	Mean	SD	Mean	SD	Effect Size (T1, T2) (Cohen’s d)	N^* for (T1, T2)	Effect Size (T1, T3) (Cohen’s d)	N^* for (T1, T3)
Controls	14.88	30.98	12.82	30.30	9.91	39.15	0.08	1229	0.19	220

Note:

The sample size needed to reach 80% of the power based on the effect size.
