After publication of the original article [1], the authors have reported that the software developers had used a new amended version of the software called “v0.9.5.10” instead of “v0.9.5.5”, which is referred to in the original article.

Thus, the authors have conducted trial sequential analysis with new version of the software for the two continuous end-points. All corrections are following:

1. “v0.9.5.5” in the Trial sequential analysis (methods section) is corrected to “v0.9.5.10”.

2. The estimated required information size of Length of hospitalization (7161, results section) is corrected to “7242”.

3. Fig. 5 is below updated.

The conclusions are as same as published in the original article.
