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

backgroundThe purpose of this study was to compare behavioral, psychosocial, and neighborhood environmental factors of long-term weight loss maintainers in North America and Europe.

methodsParticipants were weight loss maintainers in WeightWatchers in North America (n = 3656) and Europe (n = 624) who had maintained a ≥ 9.1 kg (21.7 kg on average) weight loss for ≥1 year (5.3 years on average) and had a current mean BMI of 29.9 kg/m

resultsWeight loss maintainers in North America vs. Europe had higher odds of weekly self-weighing (95% vs. 91%; OR = 1.7 [95% CI: 1.1, 2.5]), eating at fast food restaurants ≥weekly (11.6% vs. 2.6%; 7.7 [3.9, 14.3]; p < 0.001]), and other restaurants (29.7% vs 17.3%; OR = 1.47 [1.2, 2.1]; p < 0.001), more positive scores for body image (21.4 vs.20.7; η

conclusionsWeight loss maintainers in North America and Europe differed in restaurant eating and self-weighing practices but otherwise reported similar behavioral, psychological, and environmental strategies.
