TABLE 3.

Best predictors of post-operative complications based on the multivariable regression model.

Parameters	OR	95% CI
Peripheral artery disease	1.90	1.08 to 3.37
Bilobectomy (vs. sublobar)	3.44	1.20 to 9.85
Pneumonectomy (vs. sublobar)	10.32	3.29 to 32.35
Preoperative FEV₁ (% predicted)	0.98	0.97 to 1.00
Peak $\dot{V} O_{2}$ (ml⋅kg⁻¹⋅min⁻¹)	0.92	0.86 to 0.98
Peak $\dot{V} E$ / $\dot{V} C O_{2}$	1.04	1.01 to 1.07

Definitions of abbreviations: OR = odds ratio; CI = confidence interval; FEV₁ = maximal forced expiratory volume in 1 s; Peak $\dot{V} O_{2}$ = oxygen uptake at peak exercise; Peak $\dot{V} E$ = ventilation at peak exercise; $\dot{V} C O_{2}$ = carbon dioxide excretion at peak exercise.
