The source adds the following information:
All analyses assessing lifetime self-reported concussion used custom weights to adjust for the different sample sizes for 8th-, 10th-, and 12th-graders. All analyses accounted for the complex sampling design.
Concussions were reported across each participant’s lifetime.
On the measure that assessed concussion, 4.9% of the sample had missing data. Percentages and 95% CIs are based on weighted data; sample sizes are based on unweighted data.
The data collection stopped early on March 14, 2020, due to COVID-19. Values indicate approximately one-third of a typical annual data collection.
