B Proportion of NIH-funded studies assigned scores between 0 and 6 in 1999, 2009, and 2019. C Proportion of non-NIH-funded studies assigned scores between 0 and 6 in 1999, 2009, and 2019. D Scores assigned to studies that declared NIH funding in the biomedical and clinical disciplines in 1999, 2009, and 2019 (ns not significant; generalized linear model with Poisson distribution; error bars indicate SEM)
