Descriptive Statistics (Compensated MAE, Newtons)
----------------------------------------------------------------------
                         Inspiration      Expiration      Diff (E-I)
Veridical            0.260 +/- 0.110   0.227 +/- 0.068   -0.033 +/- 0.093
Perturbed (2x)       0.577 +/- 0.307   0.499 +/- 0.336   -0.078 +/- 0.314

Paired t-tests: Expiration vs Inspiration (within condition)
----------------------------------------------------------------------
                            t   df        p        d
Veridical              -1.718   23   0.0992   -0.358
Perturbed (2x)         -1.215   23   0.2368   -0.253

Factorial Effects (Condition x Phase)
----------------------------------------------------------------------
Condition (Pert vs Verid):  t=-4.954, p=0.000010
Phase (Exp vs Insp):       t(47)=1.662, p=0.1031
Condition x Phase:         t=-0.677, p=0.5020

Phase Asymmetry x Session (Spearman rho)
----------------------------------------------------------------------
Veridical            rho=+0.280, p=0.1852
Perturbed (2x)       rho=-0.081, p=0.7076
