^*Odds ratios were obtained by exponentiating the coefficients from Cox proportional hazards regression models. The 95% confidence intervals were obtained using a modified method of balanced repeated replications to adjust for stratification, clustering, and weighting of the data. A single model was estimated for each of the 6 outcomes that included all of the predictor variables.

^†The behavioral categories of attempt and ideation present the risks for the unconditional behaviors.

^‡The behavioral categories of plan among ideators, impulsive attempt among ideators without a plan, and planned attempt among ideators with a plan present the risks for the conditional behaviors.

^§P< .05 by a 2-sided test.

^∥Wald χ² values were obtained from design-based variance-covariance matrices to adjust for the stratification, clustering, and weighting of the data.
