Correlation coefficients between ITPC1 and edge markers.

Edge markers	r	p
Sharpness	0.6	0.018 *
Maximum Amplitude (MA)	0.31	n.s.
MA Latency	–0.75	0.001 **
80% of MA Latency	–0.76	<0.001 ***
Plateau	0.51	0.051
Gini Index	–0.61	0.016 *
Maximum derivative (MD)	0.37	n.s.
MD Latency	–0.85	<0.001 ***

The correlation coefficient r and its significance p where calculated in the usual way:

^* p < 0.05,

^** p < 0.01,

^***p < 0.001.
