Adherence
The efficacy of the vegetable consumption app is moderated by baseline vegetable intake; users with higher baseline consumption benefit significantly more from the intervention.
If you already eat a decent amount of vegetables, a tracking app will likely boost your intake even more than if you eat few vegetables. The app's gamification resonates more with those who already value vegetables.
GoodQualifiesHIGH confidence
Baseline vegetable consumption was a significant moderator of intervention effects (p=0.002) in which effects increased as baseline consumption increased.
Why this rating
