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

objectiveTo characterize perceived barriers to healthful eating in a sample of obese, treatment-seeking adults and to examine whether changes in barriers are associated with energy intake and body weight.

designObservational study based on findings from a randomized, controlled behavioral weight-loss trial.

participantsParticipants were 113 women and 100 men, mean age 48.8 years, 67% white, and mean body mass index at baseline 34.9 kg/m(2). VARIABLES MEASURED: Perceived diet barriers were assessed using a 39-item questionnaire. Energy intake was assessed with the Block Food Frequency Questionnaire. Body weight (kg) and height (cm) were measured. ANALYSIS: Factor-based scales constructed from exploratory factor analysis. Linear regression models regressed 12-month energy intake and body weight on baseline to 12-month factor-based score changes (α = .05).

resultsExploratory factor analysis yielded 3 factors: lack of knowledge, lack of control, and lack of time. Reported declines in lack of knowledge and lack of control from baseline to 12 months were associated with significantly greater energy restriction over 12 months, whereas reported declines in lack of control and lack of time were associated with significantly greater weight loss. CONCLUSIONS AND IMPLICATIONS: Results suggest that declines in perceived barriers to healthful eating during treatment are associated with greater energy restriction and weight loss.
