1 · What the graph read from 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.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectiveThe Mobile Lifestyle Intervention for Food and Exercise (mLIFE) study was a 12-month mobile weight loss intervention examining social gaming to promote social support.

methodsAdults with overweight or obesity (n = 243) were randomized to the mLIFE + points (received points for social support activities) or mLIFE group (blinded to points). Weight was measured via Fitbit scales. Repeated-measures mixed models were used to conduct both an intent-to-treat analysis and an analysis among adherent participants (logged on to the mLIFE app ≥25% of study days).

resultsAttrition was lower in the mLIFE + points group (22% vs. 41% in mLIFE; χ

conclusionsThe use of points led to greater weight loss at 12 months, but only among adherent participants. Providing points for completing social support activities is a way to retain participants and increase engagement in a mobile intervention.
