Estimates of vaccine efficacy from meta-analysis and combined results used in the model. Shown are risk ratios and 95 % confidence intervals. The size of the red squares indicates the relative influence of the trial on the combined estimate; trials of large sample size will have a higher impact compared to trials of smaller sample size. The black diamond illustrates the combined estimate for each outcome; its width is a measure of the associated uncertainty
