Figure 1 . Exercise test interpretations for all 259 pectus
patients performing CPET (A) and subset of patients reporting dyspnea on
exertion (B). Mild reduced fitness defined as peak VO270-79%, moderate 60-69%, and moderate-severe 50-59%. Abbreviations:
CPET (cardiopulmonary exercise tests), VO2 (oxygen
consumption).
Figure 2 . Pulmonary function testing interpretation and
classification for all patients performing maximal CPET. Two patients
had mixed obstruction and restriction and were classified as
restrictive. Degree of obstruction based on the FEV1 and
defined as mild > 70% up to 95% ci; moderate 60-69%;
moderate-severe 50-59%. Degree of restriction or NSVL based on the FVC
and defined as mild > 70% up to 95% ci; moderate 60-69%.
Abbreviations: CPET (cardiopulmonary exercise tests).
Figure 3 . Scatterplots comparing the correction index with total
lung capacity (TLC, Panel A), peak VO2 (Panel B),
breathing reserve (BR, Panel C) and ratio of tidal volume to inspiratory
capacity (Vt/IC, Panel D). Abbreviations: TLC (total lung capacity),
VO2 (oxygen consumption), BR (breathing reserve), Vt
(tidal volume), IC (inspiratory capacity).
Figure 4 . Linear regression final model results with
VO2 peak as outcome (Panel A). Negative (-) indicates an
inverse relationship between variable and VO2 peak.
Scatterplot of Vt/IC and VO2 peak (Panel B) comparing
female versus male. Abbreviations: FEV1 (forced
expiratory volume at 1 second), VO2 (oxygen
consumption), BR (breathing reserve), Vt (tidal volume), IC (inspiratory
capacity).
