^aSentinel event defined as an episode of sexual touching or attempted sex occurring before an episode of unwanted completed sexual intercourse, all events in childhood before the age of 18. Sample includes those individuals who have complete information on sentinel events and unwanted sex. Those individuals experiencing a potential sentinel event in the same year as unwanted completed sex were coded as missing and not analyzed given the inability to determine which was the initial event.

^bAmong those children having experienced a sentinel event.
