t-test: paired two sample for means (pulse).

Indicator	${\mathit{M}}_{\mathit{s}}{}^1$	${\mathit{M}}_{\mathit{e}}{}^2$	P 3	ΔI 4
$\mathit{P}\mathit{u}\mathit{l}\mathit{s}\mathit{e}$	92.08	89.31	0.002	−3.49

¹ Where $M_s$ is the initial mean, ² $M_e$ is the final mean, ³ p is the significance, and ⁴ ΔI is the increment of the indicator between the final mean and the initial mean.
