^{1, 4} and ⁷ Mean values of patients who had mild COVID-19 symptoms on first, second and third months were compared with repeated measure ANOVA (between groups): F(2,68)=29.13, p<0.001.

^{2, 5} and ⁸ Mean values of patients who had moderate COVID-19 symptoms on first, second and third months were compared with repeated measure ANOVA (between groups): F(2,74)=32.23, p<0.001.

^{3, 6} and ⁹ Mean values of patients who had severe COVID-19 symptoms on first, second and third months were compared with repeated measure ANOVA (between groups): F(2,23)=32.23, p<0.001.

The mean SF36 scores of mild, moderate and severe groups in each month were compared with one-way ANOVA. There was a statistical significant difference (p<0.05) for all the dimensions within groups in each month.

^{a, b} and ^c Significant categories within the month based on post-hoc tests (Tukey).

*3 patients died and 14 patients were lost to follow-up within 1 mo.

**3 patients died and 3 patients were lost to follow-up within 1–2 mo of discharge.

***1 patient lost to follow-up within 3 mo of discharge.

^$5 lost to follow-up.

^$$1 lost to follow-up.

^$$$5 lost to follow-up.
