The normally distributed variables for the systemic and cerebral circulation measurements were compared using a paired Student's t-test between the 500 and 3700 m altitudes and were analyzed using an independent samples t-test between the HAH positive (HAH+) and HAH negative (HAH-) groups at both altitudes.
The pulsatility index (PI) and resistance index (RI) of left VA were lower in the HAH subjects (p < 0.05) and were negatively correlated with HAH (p < 0.05).
However, only the HAH model can capture transients after double SPCs qualitatively for low carbon steels.
The HAH patients were also characterized by increased HR and CO.
The asymmetry of the bilateral VAs, including the ΔVd (p = 0.010), ΔVm (p = 0.046) and AI (p = 0.040), in the HAH patients was significantly different than the HAH- subjects.
The HAH patients were characterized by an increased Vd but decreased RI and PI in the left VA.

Only age (p = 0.044) was significantly higher in the HAH+ group as compared with the HAH- group regarding demographic data.
Although the LA, LV, RA, RV, PA, EF, SV and tricuspid regurgitation were not significantly different in the HAH+ subjects compared with the HAH- subjects (all p > 0.05), the CO was significantly increased in the HAH+ group (p = 0.001).
Furthermore, the Vd in left VA was significantly increased in the HAH+ group compared with the HAH- group (25.96 ± 4.97 vs. 24.76 ± 4.76 cm/s, p = 0.045), whereas the Vs and Vm were not significantly different between the two groups.
Regarding blood pressure, there was no significant difference between the HAH+ and HAH- groups in the SBP, DBP, pulse pressure or mean arterial blood pressure.
Similar to the MCA, the PI (p = 0.151) and RI (p = 0.292) of the BA were not significantly different between the HAH+ and HAH- groups.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
