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 examine associations of objectively-measured physical activity (PA) with changes in weight after roux-en-Y gastric bypass (RYGB) over 7 years.

backgroundThe contribution of free-living PA to surgery-induced weight loss and subsequent weight regain is not well understood.

methodsParticipants of a multi-center prospective cohort study of bariatric surgery were followed annually ≥7 years. Of 807 participants who underwent RYGB and were given an activity monitor, 649 (80%) had sufficient data for this report (78% female; median age 47 years; median body mass index 46 kg/m2). Mean daily steps, hours/day in SB and minutes/week in moderate-to-vigorous physical activity (MVPA) were determined at each assessment. Mixed models tested associations between PA measures and weight outcomes, controlling for sociodemographics, health status, and eating behaviors.

resultsAcross follow-up, mean pre to postsurgery changes in PA were small, and mean postsurgery PA level was below PA recommendations for health (eg, 101 MVPA min/week 7 years postsurgery versus the ≥150 MVPA min/week recommendation). There was a dose-response association between more steps, less SB and more MVPA with greater weight loss. Steps and SB, but not MVPA, were also associated with weight regain. For example, participants in the highest versus lowest steps quartile lost 2.9% (95% confidence interval, 1.8-4.1) more of their presurgery weight and regained 5.4% (95% confidence interval, 2.4-8.3) less of their maximum weight lost across follow-up.

conclusionsDespite only small increases in objectively-measured PA level after RYGB, PA level was independently associated with weight outcomes of bariatric surgery throughout 7 years of follow-up. REPRINTS: Reprints will not be available from the authors.
