Meta-Regression: Year of Publication.

This figure shows the association between the year of publication and intervention efficacy for A) knee injury and B) ACL injury. Publication year is along the X-axis, and each dot represents the summary IRR for that year. The size of the bubble corresponds to the average sample size for studies published in that year.

本图展示了(A)膝关节损伤与(B)前交叉韧带（Anterior Cruciate Ligament，ACL）损伤的发表年份与干预效果之间的关联。横轴为发表年份，每个圆点代表对应年份研究的综合发病率比（Incidence Rate Ratio，IRR）；气泡大小则与该年份发表的各项研究的平均样本量相对应。
