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

backgroundA substantial proportion of severely obese patients undergoing bariatric surgery have not developed disease as a consequence of obesity. Little is known about the effects of bariatric surgery on health-related quality of life (HRQL) in this patient group. In a prospective study at a public hospital, we compared HRQL in gastric bypass patients with and without obesity-related disease before and 2 years after surgery.

methodsHRQL was assessed in 232 severely obese patients before, 1 year, and 2 years after Roux-en-Y gastric bypass. We used a general HRQL questionnaire, the Short Form 36, and an obesity-specific questionnaire, the Obesity-related Problems scale. The patients were divided into two groups based on the presence of obesity-related disease (n = 146) or not (n = 86) before surgery. We defined obesity-related disease as having at least one of the following conditions: type 2 diabetes mellitus, hypertension, dyslipidemia, coronary heart disease, obstructive sleep apnea, gastroesophageal reflux disease, or osteoarthritis. Linear mixed models were used to analyze the HRQL outcomes.

resultsBefore surgery, patients with no obesity-related disease reported equal HRQL compared with patients with obesity-related disease. Two years after gastric bypass, substantial improvements in all subscales of Short Form 36 and in Obesity-related Problems scale were observed in both groups, and the improvements were similar in 7 out of 8 subscales of Short Form 36 as well as for the Obesity-related Problems scale.

conclusionsBaseline HRQL was similar in patients with and without obesity-related disease prior to gastric bypass. After surgery, patients with no comorbidity had similar positive changes in HRQL as patients with one or several comorbidities. These findings indicate that other factors than obesity-related disease are at least as important for severely obese patients' impaired HRQL.
