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

backgroundRoux-en-Y gastric bypass is a surgical technique widely used in the treatment of obesity. It is unclear, however, if the length of the biliopancreatic and alimentary limb interferes with the magnitude of weight loss.

aimTo evaluate if the length of these limbs is related to the percentage of weight loss one year after surgery.

methodOne hundred and twenty obese people underwent surgery between 2009 and 2011. Patients were inserted into four groups: A) biliopancreatic limb with 50 cm length and alimentary limb with 100 cm length; B) biliopancreatic limb with 50 cm length and alimentary limb with 150 cm length; C) biliopancreatic limb with 100 cm length and alimentary limb with 100 cm length; D) biliopancreatic limb with 100 cm length and alimentary limb with 150 cm length. Age, gender, body mass index and the percentage of total weight loss were analyzed. Data were collected preoperatively and one year after surgery. The groups were compared and weight loss compared between groups.

resultsThe follow-up occurred in 78.3% of the sample. The composition of the groups was similar, with no statistical significance. The average age was 43 years in groups A, C and D and 42 years in group B. The female gender predominated in all groups (about 60% of the sample). The mean body mass index was 46 kg/m2 for groups A, C and D and 42 kg/m2 in group B. The percentage of weight loss was 33% for group A and 34% for groups B, C and D. There was no significant difference among groups.

conclusionDifferent lengths of the biliopancreatic and alimentary limbs did not affect the percentage of total weight loss.
