	300	−0.5 (−0.77–−0.13)
Per-peak	20	−15.5 (−17.69–−13.39)	0.0014
	120	−12.9 (−15.04–−10.74)
	300	−9.0 (−11.12–−6.83)
Per-steady	20	−7.6 (−8.79–−6.38)	0.0651
	120	−6.4 (−7.62–−5.21)
	300	−5.5 (−6.74–−4.33)
Post-peak	20	5.4 (4.57–6.16)	0.0001
	120	4.0 (3.22–4.81)
	300	2.2 (1.43–3.02)

The p-value is the main effect of each period.
