*P<0.05 is significant; χ2 test for nominal values. Independent t-test for continuous values. Missing values were <3% for all variables except did alcohol contribute? (27.1%) and mechanism of injury (15.1%, across all trauma cases), the proportion of missing values for these variables was similar across both pre-lockdown and lockdown periods. Percentages may not add to 100% due to rounding.
