Lasagne plot for the predicted probabilities for individual health behaviours at Sessions 1, 5 and 6. Notes: (a) Fruit and vegetables (highest =  ≥ 2 serves fruit and ≥ 5 serves veg, lowest =  < 2 serves fruit and < 5 serves veg); (b) Sugar-sweetened beverages (highest =  < weekly; lowest =  > weekly); (c) Take-away (highest =  < weekly; lowest = daily); (d) Alcohol quantity (highest = none; highest =  ≥ 5 drinks per session); Alcohol frequency, (highest = daily; lowest = less than daily; (e) Smoking (highest = never smoked; lowest = current smoker); (f) Physical activity (highest = sufficiently active for health; lowest = sedentary); (g) The predicted probabilities from nominal logistic models were fitted separately for each health behaviour. Adjustment was made for study modality, no. sessions, time, employment status, sex, age bracket, educational attainment, First Nations People, and IRSAD quintile
