Evaluation of gastric fundus invagination for weight loss in a porcine model.
Article in Obesity surgery, 2012. 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
Gastric fundus compliance allows stomach volume increase in response to food intake. Absence of this postprandial relaxation alters hormonal signals and induces early satiety and weight loss. This study demonstrates the effect of gastric fundus invagination on the growth rate of juvenile pigs. After institutional animal care and use committee approval, 15 juvenile pigs were divided into two groups. In the first group, six pigs were anesthetized, weighed, and submitted to laparotomy, stomach manipulation, and short gastric vessel ligation. This is the control group and is referred to as "Sham". In the second group, gastric fundus invagination was added by using a circular stapler. This is the procedure group and is designated as "GFI". Postoperatively, body weight and food intake were measured for 5 weeks. Pigs were euthanized and the stomachs examined. Growth patterns were compared. Three animals were excluded from the analysis. At the end of the 5-week study period, six GFI pigs had intact anastomosis with an invaginated fundus. The mean percent growth rate for the GFI group (54.2 ± 2.8 %) was significantly less than the Sham group (77.7 ± 4.9 %). Gastric fundus invagination significantly decreases the growth rate in juvenile pigs.
