Figure 1).Statistical AnalysisThe data have been excluded if the subjects’ demographic information and facts along with other things have been incomplete. The typically distributed variables had been expressed as implies SD. The non-normally distributed variables were expressed as medians (Quartile 1 and 3). The ePAP group was defined as an mPAP greater than 25 mmHg based on the literature. The subjects happen to be divided into two groups (ePAP+ and ePAP- groups) as outlined by the cutoff value of mPAP at high altitudes. Differences inside the variables amongst the ePAP+ and ePAP- groups were assessed utilizing independent sample t-tests or Mann hitney U testsFrontiers in Cardiovascular Medicine | frontiersin.orgJune 2022 | Volume 9 | ArticleBian et al.Baseline NO and Ang II Levels Predict ePAPFIGURE 2 | Flowchart of this study.as acceptable. The association between the variables plus the mPAP was analyzed using Spearman correlation evaluation.NAMPT Protein custom synthesis An adjusted logistic regression analysis was performed to identifyindependent risk aspects for ePAP (i.e., these variables for which the p-value was significantly less than 0.01 in the univariate analyses or p 0.05 inside the partnership analysis or p 0.05 in theFrontiers in Cardiovascular Medicine | frontiersin.orgJune 2022 | Volume 9 | ArticleBian et al.Baseline NO and Ang II Levels Predict ePAPFIGURE three | Adjustments inside the pulmonary artery acceleration time (PAT) and mean pulmonary artery stress (mPAP) distributions.
