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
backgroundBariatric surgery is the most effective long-term treatment for morbid obesity, reducing obesity-associated comorbidities. The purpose of the present study was to evaluate Lys656Asn polymorphism of leptin receptor gene on outcomes 1 year after biliopancreatic diversion.
methodsA sample of 41 morbidly obese patients (body mass index (BMI) > 40 kg/m(2)) were operated on. Biochemical and anthropometric evaluation were realized at basal visit and at each visit. The frequency of patients with diabetes mellitus, hypertension, and hyperlipidemia was recorded at each visit.
resultsThirty-two patients (78%) had genotype Lys656/Lys656, eight patients (19.5%) Lys656/Asn656 genotype, and one patient (2.4%) Asn656/Asn656 genotype. In the wild-type group, body mass index, weight, glucose, total cholesterol, LDL cholesterol, triacylglycerol, and systolic blood pressure decreased. In the mutant group, the same parameters improved. Initial weight percent loss at 1 year of follow-up was higher in mutant group than in wild-type group (38.9% vs 29.9%; p < 0.05). Total weight loss was higher in mutant group than wild-type group (50.7 vs 37.2 kg; p < 0.05). Basal weight and BMI were higher in mutant group than wild type.
conclusionWeight loss was higher in mutant group (Lys656Asn and Asn656Asn) than wild-type group (Lys656Lys) after bariatric surgery. Carriers of the allelic variant (Asn) had higher basal weight.
