Table 1.
The difference in demographic and post-concussive symptom scores among non-AI patients, AI patients and HCs.
| Clinical parameters | Non-AI patients (n = 32) | AI patients (n = 16) | HCs (n = 32) | P value |
|---|---|---|---|---|
| Age (year) | 37.03 ± 10.65 | 32.06 ± 10.00 | 37.78 ± 9.81 | 0.172a |
| Gender (male/female) | 22/10 | 10/6 | 20/12 | 0.848^ |
| ETPT (h) | 51.03 ± 39.26 | 110.13 ± 105.93 | – | 0.071b |
| RPQ scores | 10.06 ± 6.69 | 9.06 ± 5.58 | – | 0.588& |
| The etiologies of patients with mTBI (n = 48) | ||||
| Assault (n = 15) | 9 | 6 | – | – |
| Struck by vehicle (n = 24) | 19 | 5 | – | – |
| Falling (n = 6) | 3 | 3 | – | – |

mTBI = mild traumatic brain injury, AI = axonal injury, RPQ = Rivermead Post-Concussion Symptoms Questionnaire.
a
The difference of age among the three groups (non-AI group, AI group and healthy control group) was explored using a one-way analysis of variance.
b
The difference in ETPT between non-AI group and AI group was explored using Mann-Whitney U test.
^
The difference of gender among three groups (non-AI group, AI group and healthy control group) was explored using the Chi-square test.
&
The difference in RPQ scores between non-AI and AI groups was explored using the two independent sample t-test.
