The gross associations (odds-ratios) of baseline smoking-related predictors with subsequent SROs were found generally not to differ in predicting SRO onset and persistence. (Detailed results available on request) As a result, we focus here on pooled associations that combine the prediction of onset with the prediction of persistence. A total of eight separate baseline smoking-related variables were considered one at a time in models to predict subsequent SROs: lifetime smoking, age of first use, lifetime daily smoking, age of first daily use, frequency-recency of lifetime use (non-daily lifetime use, past daily use, current daily use), lifetime nicotine dependence, age of first dependence, and recency of dependence. A total of 17 regression coefficients were estimated to examine the associations of these eight variables with each of the subsequent SROs. (Table 2) All of these coefficients are elevated, 70% of them (12/17) significantly so at the .05 level, in predicting suicide ideation. A somewhat smaller proportion (88%) are elevated, 17% of them (3/17) significantly so, in predicting suicide plans. Only slightly more than half of the coefficients (58%), in comparison, are elevated
