Maxillofacial injuries and violence against women.

Objective: To determine if patterns of facial injuries differed between those of female assault victims with maxillofacial injuries and those of female patients with maxillofacial injuries from other causes.

Methods: We reviewed the medical and dental records of 326 adult female facial trauma patients treated by otolaryngologists and oral/maxillofacial surgeons at the University of Kentucky Medical Center. Information abstracted included date of injury, dates of presentation for medical attention, mechanism(s) of injury, diagnoses, and treatments.

Probability estimation when some observations are grouped.

This paper considers the use of additional questions for decreasing survey non-response rates and an approach for estimating a probability based on the results obtained. In a survey, the respondents are asked to answer an original question and follow-up questions, where the answers for the follow-up questions are grouped answers for the original question. For example, respondents are asked to provide an exact number of incidents, but in cases of 'Do not know' or 'Refuse' responses, they are subsequently asked to pick an answer from a less specific categorical scale.
