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.

Abstract

backgroundThe Bari-Active trial found that a physical activity (PA) intervention (PAI), versus standard presurgical care control (SC), produced significant increases in daily bout-related moderate-to-vigorous PA (MVPA, in≥10-min bouts) preoperatively. The present study examined whether PAI also produces superior improvements in psychological and/or motivational processes that may be important for PA adoption.

objectivesCompare PAI and SC on baseline to postintervention changes in PA-related enjoyment, self-efficacy, and motivations, and examine whether greater bout-related MVPA changes are associated with greater improvements in these variables.

settingUniversity hospital, United States.

methodsParticipants (87% female; body mass index = 45.0±6.5 kg/m(2)) were randomly assigned to 6 weeks of PAI (n = 40) or SC (n = 35). PAI received weekly counseling sessions to increase daily walking exercise. At baseline and postintervention, both groups completed 7-day objective PA monitoring and questionnaires to evaluate changes in bout-related MVPA and PA enjoyment, self-efficacy, and motivation.

resultsRetention was 84% at postintervention. Intent-to-treat analyses showed that PAI on average reported more favorable changes than SC in PA enjoyment, self-efficacy, amotivation (i.e., lack of PA motivation), and identified and intrinsic regulations (i.e., more autonomous PA motivations; P<.01). In PAI completers (n = 33), changes in bout-related MVPA and psychological/motivational variables were unrelated.

conclusionPAI produced greater improvements in PA-related enjoyment, self-efficacy, and motivations than SC. The lack of association between objectively measured PA changes and psychological/motivational processes highlights the need for future research to identify which processes are most important for PA adoption and maintenance in bariatric surgery patients, and to determine whether the method used to measure PA affects the pattern of association.
