Demographic | Non-blast mean (SD, n) | Blast mean (SD, n) | p-value |
---|---|---|---|
Age | 37.4 (8.5, 41) | 37.4 (8.5, 41) | >0.1 |
Days post injury | 2.0 K (1.5 K, 41) | 1.7 K (1.1 K, 41) | >0.1 |
LOC | 71% (N/A, 41) | 71% (N/A, 41) | >0.1 |
PTA | 37% (N/A, 41) | 17% (N/A, 41) | <0.05 |
AOC | 54% (N/A, 41) | 51% (N/A, 41) | >0.1 |
Education | 14.0 (2.2, 37) | 14.0 (2.3, 26) | >0.1 |
n | 41 (N/A) | 41 (N/A) | N/A |
Reported numbers of means of demographics or percentages of TBI related variables, having within parentheses the standard deviations and number of subjects. The subjects that were noted to have experienced a loss of consciousness (LOC), post traumatic amnesia (PTA), and/or alteration of consciousness (AOC) post injury are listed in percent of n. The p-values were calculated by the two-sample t-test, except from LOC, PTA and AOC that were tested using the chi-squared test.
Legend: SD, standard deviation; n, number of subjects; K, 1000; N/A, not applicable; Education, years of education from elementary school through post-graduate level, with 12 representing the conclusion of 12th grade.
