Cost and Health Care Utilization Implications of Bariatric Surgery Versus Intensive Lifestyle and Medical Intervention for Type 2 Diabetes.
Trial report in Obesity (Silver Spring, Md.), 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers, 1 of them a synthesis that pooled 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.
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
objectiveThe aim of this study was to compare the cost and health care utilization of patients with obesity and type 2 diabetes mellitus (T2DM) randomized into either Roux-en-Y gastric bypass (RYGB) surgery or an intensive lifestyle and medical intervention (ILMI).
methodsThis analysis (N = 745) is based on 2-year follow-up of a small randomized controlled trial (RCT); adult patients with obesity and T2DM were recruited between 2011 and 2012 from Kaiser Permanente Washington. Comparisons were made for patients randomized into either RYGB (N = 15) or ILMI (N = 17).
resultsThere were no significant cost savings for RYGB versus ILMI patients through the follow-up years. Pharmacy cost was lower for RYGB versus ILMI patients by about $900 in year 2 versus year 0; however, inpatient and emergency room costs were higher for surgery patients in follow-up years relative to year 0. Median total cost for nonrandomized patients was higher in year 0 and in year 2 compared to randomized patients.
conclusionsBariatric surgery is not cost saving in the short term. Moreover, the costs of patients who enter into RCTs of RYGB may differ from the costs of those who do not enter RCTs, suggesting use of caution when using such data to draw inferences about the general population with obesity.
