Corrigendum

In the paper by Dong et al.,¹ there was a mistake in the Statistical Analysis under Method section. The sentence ‘Hospitalization for HF, pulmonary diseases, non-HF CV diseases, and other reasons were treated as time-dependent covariates, for the status of hospitalization changed over time’ should not have been included. Hospitalization was not included as time-varying variables in this model. Corresponding results presented in Tables 3 and 4 were yielded from Cox models without time-varying variables. Similarly, in the Abstract, the regression model was mistakenly described as ‘time-varying Cox proportional hazards model’. The word ‘time-varying’ should not have been used.

The authors apologize for the mistake and the misleading information.
