RESULTS
At the eight emergency departments, 282 intentionally injured women and 749 control women were identified as eligible to participate in the study, and 256 (90.8 percent) and 659 (88.0 percent), respectively, agreed to participate. The age and race or ethnic group of women who declined to participate were similar to those of the women who agreed to participate. We did not record specific reasons for non participation. Among the various study sites, the number of intentionally injured women ranged from 12 to 61, and the number of controls ranged from 20 to 244. The percentages of missing values ranged from 0.2 percent to 6.0 percent (average, 2.0 percent). The baseline characteristics of the women and their partners are presented in Table 1.
