Tabled values are the estimated proportions and 95% CI of NIH projects funded as grants or cooperative agreements that supported primary and secondary prevention research in human, as well as related methods research for FY2012–2017, based on the rationales coded for each project. The topics are ranked based on average proportion of prevention projects coded for each rationale and the table presents the top ten; the complete table is provided in Appendix Table 1.
b
With 128 tests for trend, the test is significant only if p-trend<0.00039.
