a The baseline yearly number of injuries was calculated from the average of the yearly number of injuries observed in 2018 and 2019. The term “estimated” refers to weighted national estimates derived from the NEISS national consumer database described in the study methodology. Percentages may not add to 100% due to rounding error. ED, emergency department; NEISS, National Electronic Injury Surveillance System; OR, odds ratio.
b Between March 1, 2020, and May 31, 2020.
c ORs with a P value ≥ .05 are considered not significant and are marked in bold.
