The revised version of the Baveno classification. Details about symptom and comorbidity criteria are provided in the supplementary material. ESS: Epworth Sleepiness Scale. Reproduced from Randerath et al. [30].
- FIGURE 2
Flow-chart of the inclusion process. ESADA: European Sleep Apnoea Database; PAP: positive airway pressure; PSG: polysomnography; PG: polygraphy; AHI: apnoea–hypopnoea index; SysBP: systolic blood pressure; DiaBP: diastolic blood pressure; CPAP: continuous positive airway pressure; APAP: automatic positive airway pressure.
- FIGURE 3
Distribution of the Baveno groups A–D in different apnoea–hypopnoea index (AHI) groups and in the overall patients.
- FIGURE 4
Changes in systolic and diastolic blood pressure (BP) between baseline and follow-up in the different Baveno groups A–D. Circles denote outlier values (>1.5 interquartile ranges outside the box), asterisks denote extreme values (>3 interquartile ranges outside the box). #: p<0.001 baseline versus follow-up.
- FIGURE 5
Change of the Epworth Sleepiness Scale (ESS) score between baseline and follow-up in the different Baveno groups A–D. Circles denote outlier values (>1.5 interquartile ranges outside the box). #: p<0.001 baseline versus follow-up.
- FIGURE 6
Percent of patients with positive airway pressure (PAP) prescription at baseline in the different apnoea–hypopnoea index (AHI) groups and in the whole study population. White columns represent actual PAP prescription as per conventional clinical routine decision; shaded columns represent PAP prescription as indicated by Baveno classification (i.e. Baveno groups B–D).
