The Academic Editor, Jan P. Vandenbroucke, has disclosed that he has worked with authors SG and YKL on another project unrelated to the study reported in this paper. He also discloses an intellectual competing interest in that he has previously published the theoretical viewpoint that estimates of harms outcomes in observational studies may be as valid as results of randomized trials, and may be more generalizable. The authors have no competing interests to declare.
