Author Contributions
IK abstracted baseline data from the FDA dataset, conceived the analyses, analyzed the data, and wrote the initial draft. BJD established correspondence between trials reported in the FDA dataset and those reported in the GlaxoSmithKline clinical trial register, abstracted the data from those trials, checked baseline data for trials in the FDA dataset, identified published versions of the FDA trials, and abstracted the data from those trials. TJM obtained the data from the FDA, and TJM and AS abstracted improvement data from that dataset. TBH and BTJ joined the project during the review process, analyzed the data, and assisted with subsequent drafts of the manuscript.
