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

backgroundWhether or not the initial body mass index (BMI) influences weight loss and comorbidities improvement after bariatric surgery continues to be a matter of debate. The main reason for this is a lack of studies including obesity class I.

methodsRetrospective study with patients submitted to gastric bypass at a single institution. They were classified based on initial BMI (obesity class I, II, and III), and a comparative analysis of their metabolic profile (glucose, HbA1c%, C-peptide, insulin and diabetes medication), lipid profile (triglycerides, total cholesterol, HDL, LDL), and clinical data (systolic/diastolic blood pressure and cardiovascular risk) was performed at 0 and 12 months. Diabetes remission and weight loss were also analyzed.

resultsTwo-hundred and twenty patients were included (23 in group 1, 113 in group 2, and 84 in group 3). Initial weight, BMI, and number of patients with T2DM were statistically different in group 1; other parameters were homogenous. At 12 months, every group had similar improvement of the metabolic profile, excepting serum insulin. Diabetes remission was 57.9, 61.1, and 60% for group 1, 2, and 3. For weight loss, there were differences between groups when using BMI and percentage of excess weight loss, but not with percentage of total weight loss. The non-metabolic and clinical data improved without differences, except for total cholesterol and LDL.

conclusionsThe metabolic, lipid, and clinical profiles associated with obesity present similar improvement 1 year after laparoscopic gastric bypass, despite different baseline BMI. Diabetes remission and percentage of total weight loss were also similar.
