Exhaled Nitric Oxide and Exhaled Breath Temperature as Potential Biomarkers in Patients with Pulmonary Hypertension

Figure 2

Boxplot showing CANO (alveolar concentration of nitric oxide) values in the studied groups. Thick line showing median, box showing 25% and 75% interquartile ranges, and error bars showing minimum and maximum values. Small circles indicate outlier values. Groups were compared by ANOVA and Wilcoxon test (PAH, pulmonary artery hypertension; COPD, chronic obstructive pulmonary disease; and HF, heart failure).
