Individual study and overall hazard ratios of relationships between every 4-week delay in initiation of adjuvant chemotherapy and overall survival. Individual and overall hazard ratios (HR) per 4-week of delay with 95% confidence interval (CI) for OS are shown in A. The size of each square is proportional to the weight of the study. For the combined result, the length of the diamond represents the 95% CI of the summary. B. shows the influence of individual studies on the pooled HR. The vertical axis indicates the overall HR and the two vertical axes indicate its 95% CI. Every hollow round indicates the pooled OR when the left study is omitted in this meta-analysis. The two ends of every broken line represent the respective 95% CI.
