TABLE 3.

Pulmonary function tests of patients at first follow-up visit according to presence or absence of radiological recovery at 12 months (n = 347).

	Overall population (n = 347)	REC (n = 323)	NOT-REC (n = 24)	p
FVCabs–liters	3.3 (2.8–4.0)	3.3 (2.8–4.0)	3.2 (2.4–4.6)	0.38
FVC pred–%	92 (81–104)	92 (81–104)	97 (70–103)	0.79

FEV1 pred–%	95 (84–137)	95 (84–137)	99 (55–121)	0.74

FVC: forced vital capacity, FEV1: flow expiratory volume at first second. Values are expressed as median and interquartile range (IQR). To compare the pulmonary function test between recovered (REC) and NOT-REC, the Mann–Whitney test for continuous variables was used.
