Bold values indicate significant differences (p < 0.05) in the prevalence of respective risk factors between the three consumption groups (across number of risk factors).
aCalculation of total percentage also included individuals with 0 risk factors. Underlined p values remain significant after Bonferroni correction (p < 0.05/6 = 0.008). Two-sided Chi²-test applied.
