Stress–length relation mean values for CTRL and HFSD mouse cardiomyocytes

	CTRL 2 Hz	HFSD 2 Hz	P
Systolic stress–SL relation slope ((mN/mm2)/µm)	6.54 ± 4.97	16.35 ± 15.09	0.087
Systolic stress–length relation slope ((mN/mm2)/%length)	0.013 ± 0.011	0.022 ± 0.011	0.022
Systolic: diastolic stress–SL relation ‘Frank–Starling gain index’ (ratio)	2.40 ± 1.06	2.77 ± 1.45	0.562
Systolic: diastolic stress–length relation (ratio)	1.62 ± 0.25	1.73 ± 0.50	0.471

Comparisons between two treatment groups performed using Student's unpaired t test (CTRL: N = 4–6 mice, n = 9–17 cells; HFSD: N = 2–6 mice, n = 7–19 cells). Data are presented as means ± standard deviation.
