(A) Forest plot of summary analysis of the standardized mean difference (SMD) and 95% CI of the central macular thickness between the NSAIDs group and control group. The size of the green squares is proportional to the statistical weight of each trial. The black diamond represents the pooled point estimate. The positioning of both diamonds and squares (along with 95% CIs) beyond the vertical line (unit value) suggests a significant outcome (IV = inverse variance) (B) Funnel plot of the publication bias showed symmetrical distribution of studies along the middle line
