This is the most relevant part, but it's not too informative:
"Except for helmet use, there were no statistical differences between those commuters who experienced a serious traumatic event and those who did not. Thirteen percent of commuters who did not wear a helmet experienced a serious traumatic event, compared with 5% (43) of those who did (p 0.023). In an additional analysis comparing commuters who reported a traumatic event with those who reported a serious traumatic event, lack of helmet use was the only statistical difference between the two groups (p 0.013)."
Of the 962 commuters, about 30 experienced traumatic or serious traumatic events with head injury, 35 indicated face injury, over 12 months.
It is an interesting study for other reasons, though: most traumatic events and serious traumatic events by far occurred while riding on the shoulder or in a bike lane, and on residential streets. I.e. take the lane and ride in traffic.
Don't forget, according to the authors of this article a "traumatic injury" can mean anything, and that means anything from the slightest boo-boo or less; a "serious traumatic injury" only requires any kind of medical attention. Hardly the definition of traumatic injury envisioned by anybody familiar with the English language but may be useful for a researcher with an agenda to prove.
