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

backgroundSignificant, sustained weight loss through conventional, non-surgical interventions is often unattainable for people with severe obesity (e.g. BMI ≥40 or ≥35 kg/m(2) with co-morbidities). Bariatric surgery is effective in treating severe obesity, but surgery alone without additional behaviour change management may not result in optimum long-term weight loss and maintenance. This systematic review and meta-analysis of randomised controlled trials evaluated the effectiveness of lifestyle interventions before and/or after bariatric surgery.

methodsMEDLINE, Embase, Cochrane Central Register of Controlled Trials and clinical trials registers were searched for eligible studies. Key journals were handsearched. Last search date was on December 2014. Eligible interventions had the explicit aim of changing behaviour related to diet and/or physical activity, starting within 12 months of surgery, either pre- or post-operatively, and with at least 6 months' follow-up. The primary outcome was weight change; secondary outcomes included surgical complications, quality of life and changes in co-morbidities. Random effect meta-analyses were undertaken. Study quality was assessed with the Cochrane Collaboration's risk of bias tool.

resultsEleven trials met the inclusion criteria. Behavioural interventions appear to improve weight loss at 12 months after bariatric surgery. Secondary outcome data were lacking and weight outcomes were reported inconsistently. Overall, the methodological quality of the identified trials was low.

conclusionsThe strength of evidence is limited by the relatively small number of trials identified and by their low methodological quality and short follow-up duration. Well-designed randomised controlled trials (RCTs) with long-term follow-up are required.
