Results of the fully adjusted models are displayed. Dietary outcomes: N = 403, PA outcomes N = 394. IC = intervention condition, UC = usual care control condition, ref = reference group, PA = physical activity; p fdr = controlling for false discovery rate; d = Cohen’s d (corrected for baseline value) , f 2  = Cohen’s f 2 :f 2 ≥ 0.02, f 2 ≥ 0.15, and f 2 .≥ 0.35 represent small, medium, and large effect sizes Diet behavior Effects of having access to the KNW on dietary behavior after six months Significant intervention effects on vegetable consumption using the fully adjusted MLA- model (complete cases: B = 9.15, p = .027, p fdr = .148, d = -.37, f 2 = -.013; ITT: B = 9.57, p = .023, p fdr = .160) did not remain significant after accounting for multiple testing. No significant effects of having access to the KNW were found on the other dietary behavior outcomes after six months. Results are displayed in Table 5.2.
