Note. Results were pooled from five imputed datasets; Variables entered at each step are marked in gray; ΔR² = change in R² at each step; β = standardized (beta) regression coefficients; In parentheses for significant β values is the squared part correlation or percent of unique variance in PT symptoms accounted for by the risk factor.
