Outcomes of a pilot microrandomized trial of just-in-time adaptive intervention messages nudging weight-related behaviors in young adults.
Article in Digital health. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03836391 (Precision Public Health), which is not on this map. Cited by 4 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
Objective: There is limited evidence on the effects of various types of intervention messages on achievement of daily behavioral goals in mobile weight loss programs. Nudge, a 12-week pilot microrandomized trial among young adults, tested whether 7 types of intervention messages based on behavior change techniques (BCTs) increased the likelihood of daily goal achievement. Methods: Participants received lessons, tailored feedback, self-monitoring tools, and daily messages, and had daily behavioral goals (weighing, active minutes goal, and red foods limit). Four times/day, participants (N = 52, aged 18-35, body mass index 25-40 kg/m Results: Randomization to receive any message (vs. none) did not impact likelihood of meeting daily goals overall but was associated with fewer red foods tracked (odds ratio (OR) = .96; 95% confidence interval (CI): .94-.98). Randomization to receive (vs. not receive) a social comparison message about red foods was associated with fewer red foods tracked (OR = .92; 95% CI: .85-.99); no other message types were associated with daily goal achievement. Receiving and viewing any message (vs. not viewing) increased odds of achieving daily goals for all 3 behaviors: weighing (OR = 1.91; 95% CI: 1.06-3.43), active minutes (OR = 1.63; 95% CI:1.20-2.20), and red foods limit (OR = 2.09; 95% CI:1.46-3.01). Conclusions: BCT-based messages may nudge achievement of daily goals when participants view them. Further research should explore how to increase and maintain engagement in mobile behavioral interventions.
