Site level data checks. The y-axis represents the SAE rate per site, allowing for time in the trial by patients. The lowest 10% of SAE rates are shown as black squares. The circled observation is for a site where data were faked so that the site had too few SAEs, compared to the average for all sites (horizontal line). Sites in the bottom right hand corner have lower than expected SAE rates but relatively large numbers of patients, so could have on-site monitoring checks.
