≥ 3 (vs. 1) substances	2.67 (1.23, 5.82)	1.36 (0.79, 2.34)	1.03 (0.47, 2.25)

Note. Logistic regression adjusted for sociodemographic factors and baseline past-6-month use status of respective substance use outcome. Reference group for polysubstance use was use of 1 substance. Bold indicates statistical significance following application of the Benjamini-Hochberg adjustment for multiple comparisons to control study-wise false discovery rate at .05.; Outcomes (past-6-month substance use) are presented in the first column, and predictors (cyberbullying roles) are presented in the first row.
