Trial report in Surgery for obesity and related diseases : official journal of the American Society for Bariatric Surgery, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06292936 (Evaluation of a Remotely-Delivered Behavioral Intervention for Post-Bariatric Surgery Weight Regain), which is not on this map.

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

backgroundStudies on the impact of presurgery weight loss and lifestyle preparation on outcomes following bariatric surgery are needed.

objectiveTo evaluate whether a presurgery behavioral lifestyle intervention improves weight loss through a 24-month postsurgery period.

settingBariatric Center of Excellence at a large, urban medical center.

methodsCandidates for bariatric surgery were randomized to a 6-month behavioral lifestyle intervention or to 6 months of usual presurgical care. The lifestyle intervention consisted of 8 weekly face-to-face sessions, followed by 16 weeks of face-to-face and telephone sessions before surgery; the intervention also included 3 monthly telephone contacts after surgery. Assessments were conducted 6, 12, and 24 months after surgery.

resultsParticipants who underwent surgery (n = 143) were 90.2% female and 86.7% White. Average age was 44.9 years, and average body mass index was 47.5 kg/m(2) at study enrollment. At follow-up, 131 (91.6%), 126 (88.1%), 117 (81.8%) patients participated in the 6-, 12-, and 24-month assessments, respectively. Percent weight loss from study enrollment to 6 and 12 months after surgery was comparable for both groups, but at 24 months after surgery, the lifestyle group had significantly smaller percent weight loss compared with the usual care group (26.5% versus 29.5%, respectively, P = .02).

conclusionsPresurgery lifestyle intervention did not improve weight loss at 24 months after surgery. The findings from this study raise questions about the utility and timing of adjunctive lifestyle interventions for bariatric surgery patients.
