Nirmala Ravishankar and colleagues (June 20, p 2087)1 present the results of a formidable undertaking: to collect, analyse, and track donor assistance for health for almost two decades. Although the researchers recognise and acknowledge shortcomings in their data analysis, more worrisome is that it took a monumental effort by an experienced and well connected team to complete work that should be readily available. One reason for this is that the global health architecture now includes a patchwork of private donors and foundations.
