Note: A Cox regression analysis was performed using standardized Premorbid Adjustment Scale ratings. The reference group is nonconversion. Models 1–3, the method is forced entry; Model 4, the method is stepwise backward elimination. HR, hazard ratio; CI, confidence interval.

The change from the previous step. For Model 1, this indicates the change from a univariate model with childhood as the only predictor (see Table 3). For Model 3, this indicates the change from Model 2.
