Figure 2From: Avascular necrosis in proximal humeral fractures in patients treated with operative fixation: a meta-analysisForest plots for ORs for AVN in proximal humeral fractures associated with operative fixation versus conservative treatment. Squares represent the effect size for the odds ratios of AVN in proximal humeral fractures associated with operative fixation versus conservative treatment. The sizes of the squares are proportional to the sizes of the cohorts. Error bars represent 95% confidence intervals (CIs). Diamond represents the pooled estimates within each analysis.Back to article page
