In the published article, there were errors in Figures 1, 2 and Tables 1, 2 as published. The order of the images in Figures 1 and 2 is reversed (the titles are correct, but the sequence of the images is incorrect). The first row of authors and references in Table 1, “Zhong (Zhong et al., 2021),” is incorrect. The correct citation should be “Zhu (Zhu et al., 2019)”. In Table 2, the references in the subgroup analysis for the group under 65, specifically “(Zhu et al., 2019; de Oliveira Otto et al., 2022; Wang et al., 2023)” are incorrect. They should be: “Zhong et al., 2021; Buawangpong et al., 2022; Xu et al., 2022.” The corrected Figures 1, 2 and Tables 1, 2 appear below.
