In the footnote, the author's name listed as “Manging Nie” should be “Manqing Nie” and the corrected text should read as below:
Manqing Nie and Hang Du are co‐first authors, contributed equally to this study and are listed as first authors.
In Tables 3 and 4, as the 90% confidence intervals (CIs) were calculated using bootstrap resampling, the column headings currently labeled “LL (95% CI)” and “UL (95% CI)” in both tables should be updated to “LL (90% CI)” and “UL (90% CI)”, respectively.
We apologize for this error.
