Statistically relevant changes of mass and stiffnesses (stif.) under influences of increased airflow Ug, muscular process Mp, and thyroid simulation Tc after statistical left-tail and right-tail t-tests. Within each cell, the three numbers (#-#-#) denote significant decrease (Pl < 0.05) - nonsignificant change (0.05 ≤ Pl ≤ 0.95) − significant increase (Pl > 0.95, due to Pr = 1 − Pl). The sums of the three numbers represent the amounts of mass (25), lateral stif. (25), vertical stif. (20), longitudinal stif. (20).
