Weight loss surgery for mild to moderate obesity: a systematic review and economic evaluation.

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.
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
backgroundA systematic review and economic evaluation was commissioned to determine the effectiveness and cost-effectiveness of bariatric surgery for mild [class I, body mass index (BMI) 30 to 34.99] or moderate (class II, BMI 35 to 39.99) obesity.
methodsWe searched 17 electronic resources (to February 2010) and other sources. Studies meeting predefined criteria were identified, data-extracted and assessed for risk of bias using standard methodology. A model was developed to estimate cost-effectiveness.
resultsTwo RCTs were included. Evidence from both indicated a statistically significant benefit from laparoscopic adjustable banding (LAGB) compared to a non-surgical comparator for weight loss and in obesity-related comorbidity. Both interventions were associated with adverse events. LAGB costs more than non-surgical management. For people with class I or II obesity and type 2 diabetes (T2D), the incremental cost-effectiveness ratio (ICER) at 2 years is £20,159, reducing to £4,969 at 5 years and £1,634 at 20 years. Resolution of T2D makes the greatest contribution to this reduction. In people with class I obesity, the ICER is £63,156 at 2 years, £17,158 at 5 years, and £13,701 at 20 years. Cost-effectiveness results are particularly sensitive to utility gain from reduction in BMI, factors associated with poorer surgical performance and diabetes health state costs.
conclusionsBariatric surgery appears to be a clinically effective and cost-effective intervention for people with class I or II obesity who also have T2D but is less likely to be cost-effective for people with class I obesity.
