TABLE 3.

Ordinal logistic mixed model analysis of self-reported dyspnoea by the modified Medical Research Council score at follow-up visits after discharge from hospital for COVID-19

	Univariate		Multivariable#		WHO disease severity group
	Pts./obs.	12 months versus 3 months	Pts./obs.	12 months versus 3 months	Moderate versus mild	Severe versus mild
mMRC (0, 1, ≥2)	239/415	0.76 (0.48–1.21)	239/415	0.76 (0.48–1.21)	0.63 (0.27–1.48)	0.75 (0.25–2.30)

The impact of change from 3 to 12 months and WHO disease severity are presented with odds ratio (95% CI) for being in a higher category of dyspnoea. Pts.: number of patients; Obs.: number of observations; WHO: World Health Organization; mMRC: modified Medical Research Council dyspnoea scale. ^#: adjusted for disease severity, sex and age.
