Multiple regression models: generalized linear regression model of Poisson (frequency) and ordinal logistic regressions (intensities), fixed factors: age, sex, bachelor's degree, addiction criteria, main addiction, population. Statistics: Craving frequency: n = 620; R2 adjust. = 0.183; χ2 Likelihood ratio = 142.98; df = 12; log-likelihood (difference) = 71.49; AICc = 1082.94; overdispersion = 8.26; p (model) <0.0001; Pearson adjustment (χ2) = 5012.88; p (Pearson adjust.) = < 0.0001. Craving mean intensity: n = 620; R2 (U) = 0.04; χ2 = 97.58; df = 12; log-likelihood (difference) = 48.79; AICc = 2635.34; BIC = 2731.1; p < 0.0001. Craving maximal intensity: n = 622; R2 (U) = 0.04; χ2 = 85.84; df = 12; log-likelihood (difference) = 42.92; AICc = 2097; BIC = 2192.83; p < 0.0001. FDR, false discovery rate; B, estimate association parameter; Exp, exponential. Only p-values for substances are uncorrected. Significant comparisons were marked using*; significance level: p < 0.05. Main addiction: opiate group is used as reference for analyses.
