Clinical predictors of lung function in patients recovering from mild COVID-19

BMC Pulmonary Medicine

Table 5 Variables that predict the proportion of patients who had previous COVID-19 disease with an impaired DLCO at follow-up using the mean data from 21 previous studies

Model	Unstandardized coefficient B	Coefficient S.E	Standardized coefficient Beta	t	Sig	95% confidence interval for B
Constant	− 33.47	21.08		− 1.59	0.12	− 76.5 to 9.52
History of mild vs severe COVID-19	20.55	5.26	0.49	3.91	< 0.001	0.97 to 1.03
Mean age of study (years old)	1.21	0.38	0.40	3.14	0.004	0.95 to 1.05
Criteria to define impaired DLCO	13.13	5.23	0.32	2.51	0.017	0.99 to 1.01
Mean number of days between receiving a diagnosis of COVID-19 and testing	− 0.12	0.68	− 0.23	− 1.76	0.088	0.94 to 1.06

Where mild COVID-19 = 0; Severe COVID-19 = 1; impaired DLCO defined by DLCO < LLN = 0; DLCO defined by being less than 80% of predicted = 1
