Effects of Roux-en-Y operations on glucose homeostasis in obese GK rats.
Article in Surgical endoscopy, 2011. 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
aimTo investigate the therapeutic effects of different styles of gastric bypass surgery on type 2 diabetes mellitus (T2DM) GK rats.
methodsTwenty 6-8-week-old male GK rats were randomly divided into four groups: group A was operated by Roux-en-Y gastrojejunostomy with duodenum exclusion and stomach capacity maintenance, group B was operated by loop-type gastrojejunostomy with duodenum exclusion and stomach capacity maintenance, group C was operated by Roux-en-Y gastrojejunostomy with partial gastrectomy, and group D was operated by loop-type gastrojejunostomy with partial gastrectomy. Changes of fasting blood glucose, oral glucose tolerance test (OGTT), and insulin tolerance test (ITT) in different operations were detected.
resultsThe operations exerted good effects on controlling blood glucose in groups A, B, C, and D. There was no significant difference between groups A and C (P > 0.05) or between groups B and D (P > 0.05), while operations in groups A and C were more effective than groups B and D (P < 0.05). On the 21st day after surgery, OGTT in animals of groups A and C was significantly improved, as indicated by a 34% reduction in the area under the curve (AUC) for blood glucose (P < 0.05 versus groups B and D); pregavage insulin levels (ng/ml) were significantly decreased in groups A and C (P < 0.05 versus groups B and D). The insulin tolerance test (ITT) confirmed impaired insulin sensitivity in groups B and D, compared with groups A and C.
conclusionsGastric bypass surgery might be effective to treat type 2 diabetes mellitus (T2DM), and Roux-en-Y gastrojejunostomy might be more effective than other operative styles.
