The original article [1] contained the following errors with their respective amendments:
1) Abstract, lines 48 and 49:
“Median TDI score on SST was 26.8 (IQR 23.6-29.3) in the placebo group and 28.8 (IQR 24.0-30.9) in the prednisolone group, with a median difference of 2.0 (95% CI 0.75 to 1.5).”

“Median TDI score on SST was 26.8 (IQR 23.6-29.3) in the placebo group and 28.8 (IQR 24.0-30.9) in the prednisolone group, with a median difference of - 1.5 (-3.0 to 0.25).”
2) Outcome, line 233-235:
“Median TDI score was 26.8 (IQR 23.6- 29.3) in the placebo group and 28.8 (IQR 24.0- 30.9) in the prednisolone group, with a median difference of 2.0 (95% CI 0.75 to 1.5, p = 0.10).”

3) Line 237-238:
"Self-reported smell function on VAS-score was 3.2 (IQR 1.8- 6.5) in the placebo group and 3.6 (IQR 1.0- 5.8) in the prednisolone group with a median difference of 0.45 (95% CI 1.1 to -1.2, p = 0.53)."
to
"Self-reported smell function on VAS-score was 3.2 (IQR 1.8- 6.5) in the placebo group and 3.6 (IQR 1.0- 5.8) in the prednisolone group with a median difference of 0.3 (95% CI -0.9 to -1.3, p = 0.53)."
4) Line 240-242:
“Self-reported taste function on VAS-score was 5.6 (IQR 2.3- 7.6) in the placebo group and 5.0 (IQR 2.0- 7.8) in the prednisolone group with a median difference of 0.25 (95% CI 0.1 to -0.2, p = 0.80).”
to
“Self-reported taste function on VAS-score was 5.6 (IQR 2.3- 7.6) in the placebo group and 5.0 (IQR 2.0- 7.8) in the prednisolone group with a median difference of 0.1 (95% CI -1.0 to 1.3, p = 0.80).”
