Laparoscopic adjustable gastric band: 4-year experience and learning curve.
Article in JSLS : Journal of the Society of Laparoendoscopic Surgeons. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND AND
objectivesLaparoscopic adjustable gastric banding has become the most popular procedure for the treatment of morbid obesity in Europe. The objectives of this series are to report the results of the 4-year experience of a single surgeon and to define the learning curve.
methodsA retrospective review of 156 patients who underwent laparoscopic adjustable gastric banding between October 2006 and May 2010 was performed. Patients were separated into 3 groups: group 1 comprised the first 50 patients; group 2 comprised the second 50 patients; and group 3 comprised the last group of patients, with a total of 56 patients.
resultsThe male-to-female ratio was 1:4 (33 male and 133 female patients). The mean age was 38 years (range, 17-62 years). The mean preoperative body mass index was 44.9 kg/m(2). The mean percent excess weight loss was 41.7% at the 1-year follow-up visit (153 patients, 98%), 49.7% at the 2-year follow-up visit (147 patients, 94%), and 50.2% at the 3-year follow-up visit (127 patients, 81%). The overall complication rate and major complication rate were 15.4% and 3.2%, respectively. There were no deaths. Percent excess weight loss, length of hospitalization (in days), and complication rates were compared among the 3 groups. No significant differences were noted among the groups except in the number of complications (P < .001), but all data were clearly improved in groups 2 and 3.
conclusionsThe analyses in this study have documented one more time that laparoscopic adjustable gastric banding is an effective procedure for the treatment of morbid obesity, achieving >50% excess weight loss at 3 years. It is a procedure with certain complications even when performed by a surgeon with previous experience in laparoscopic surgery. According to our subset analysis, the learning curve is at least 50 procedures.
