Significant at p<0.05 level, 2 sided test

Each trauma type was estimated as a predictor of the physical condition onset in a separate discrete time survival model controlling for person-years, age-cohorts, gender, country, education and type of physical condition.

The model was estimated with dummies for all trauma types entered simultaneously, including the controls specified above.

The model was estimated with dummy predictors for number of trauma types without any information about type of trauma, including the controls specified above.
