Figure 7 Funnel plot for bias assessment of postoperative complications in the meta-analysis. The funnel plot is used to assess publication bias for the complication outcome. The vertical axis is standard error SE(log[odds ratio]), and the horizontal axis is odds ratio. The scatter distribution of 6 studies is basically symmetric, concentrated at the top and middle of the funnel, with no obvious asymmetry, suggesting no significant publication bias. MD: Mean difference.
