Figure 2. (A) Pie chart illustrating percentage of studies analyzed that reported race as a patient characteristic. (B) Histogram reporting the percentage of studies (of the studies that reported multiple races) that reported participation rates of each race category. (C) Histogram showing percent of studies published each year that reported demographic data on participant race.
The white participants represented 82.55% (95% CI 80.39%-84.71%) of study participants (Table 1) (Figure 3A). The mean rates of participation of Asian, African American, Hispanic, Others, and Unknown were 14.03% (95% CI 11.02%-17.04%), 5.53% (95% CI 4.50%-6.56%), 3.97% (95% CI 2.13%-5.81%), 3.99% (95% CI 3.21%-4.77%), and 2.46% (95% CI 0.85%-4.08%) respectively (p < 0.001) (Table 1) (Figure 3A).
