Comparison of DCT scores

Group	RI		ΔRI	Value of p (phase 0 : 1)
	Phase 0	Phase 1
Control (n = 11)	0.606±0.049	0.616±0.054	0.0129±0.0114	<0.004
EH (n = 18) S-0	0.601±0.033	0.593±0.047	m.−0.0045 (*)
			(−0.075 : 0.048)	NS
EH (n = 18) S-1	0.591±0.042	0.592±0.034	m. 0.0030
			(−0.0455 : 0.0675)	NS

S-0 – stage 0, S-1 – stage 1
