became more robust with advancing age. The latter could reflect the shorter period of time inherent in the T20 and T25 predictions compared to T15, or the greater level of experience with alcohol that went into the SRE estimates with advancing age. Also, as was reported in a recent paper where a low LR from alcohol challenges predicted even late onset AUDs (Schuckit and Smith, 2011), the alcohol challenge results from age 20 in Table 2 significantly predicted all four adverse alcohol outcomes over the period between age 35 and 50.
