Detailed analysis of sex differences of potential precipitating events

Minor traumas within 4 weeks before the first symptom of cervical artery dissection were classified into nine groups: (A) sports activities (tennis, volleyball, judo, skiing, snowboard, cross-country skiing, sledding, soccer, riding, rollerblading); (B) recreational activities (use of roller coaster, river rafting, bungee jumping, body flying, lumbering, tuba playing); (C) coughing, vomiting or sneezing; (D) extension of neck over a hairdresser’s sink or during visit to the dentist; (E) carrying a heavy burden; (F) forced rotation of head/neck; (G) chiropractor neck manipulation; (H) other neck manipulation (by osteopath, family physician, or physiotherapist); (I) blunt minor head trauma without impaired consciousness.

The overall frequency of minor trauma and the frequencies in each subgroup of minor trauma did not differ between men and women.

Trauma
/ Men (n=399)
n (%) / Women (n=297)
n (%) / P-value
All minor trauma / 76 (19.0) / 42 (14.1) / 0.09
Sports activities (tennis, volleyball, judo, skiing, snowboard, cross-country skiing, sledding, soccer, riding, rollerblading) / 21 (5.3) / 12 (4.0) / 0.91
Recreational activities (use of roller coaster, river rafting, bungee jumping, body flying, lumbering, tuba playing) / 5 (1.3) / 5 (1.7) / 0.32
Coughing, vomiting, sneezing / 5 (1.3) / 1 (0.3) / 0.32
Extension of neck over a hairdresser’s sink or during visit to the dentist / 3 (0.8) / 0 (0) / 0.13
Carrying a heavy burden / 1 (0.3) / 1 (0.3) / 0.67
Forced rotation of head/neck / 7 (1.8) / 3 (1.0) / 0.70
Chiropractor neck manipulation / 6 (1.5) / 3 (1.0) / 0.88
Other neck manipulation
(family physician, osteopath, physiotherapist) / 5 (1.3) / 5 (1.7) / 0.32
Blunt minor head trauma / 23 (5.8) / 12 (4.0) / 0.85

P indicates the probability that the difference between both groups is significant (χ2 test)
