Statistical analysis
Statistical analysis was done using the SciPy stats package, and figure generation was done using the Matplotlib package for Python.To determine whether disparities in clinical trials’ participation exist, the mean participation rate of each race and sex across all the studies that reported race or sex was calculated, and the 95% confidence interval (CI) for the mean of each demographic was determined. Then, to compare participation rates among different races, the percent of White participation from each study was compared with the percent participation of the remaining races (Asian, African American, Hispanic, Other, and Unknown) using a two‐sample Finally, to determine how the participation rate has changed over time, the participation rates of different races from each study were plotted on a scatter plot using the Matplotlib package.
