Significant intake differences were found for legumes, tofu and soy yoghurt after the dietary intervention (week 8). The familywise error rate-adjusted Westfall-Young p-values for legumes and tofu intake were 0.001 and 0.019, respectively. Due to the unique data distribution of soy yoghurt intake in the meat-rich diet group (n = 0 vs n = 32 observations), a reliable familywise error rate-adjusted Westfall-Young p-value could not be properly computed for technical limitations. In light of the data, a significant p-value after adjustment is to be expected. NDMA: Non-Dairy Milk Alternative.
