Interrupted time series analysis evaluating intentional injuries experienced by a children of color, and b White children. The red line shows the observed, monthly total of children that were intentionally injured over time. The black dashed line represents the declaration of state of emergency (March 13, 2020) in the USA regarding the COVID-19 pandemic. The blue line is the expected monthly total number of intentionally injured children over time if there were no interruption, which in this case was initiation of stay-at-home orders. The dark and light gray represent the 80% and 95% confidence interval, respectively, associated with the expected total. Comparison of density distribution by Kolmogorov–Smirnov testing and comparison of linear trends with slope analysis demonstrate a significant increase in intentional injuries for children of color during the COVID cohort compared to the Control cohort that occurred at the start of the COVID-19 pandemic (p = 0.007). There was no significant different in intentional injuries for White children (p = 0.14)
