Sulfonylurea receptor knockout causes glucose intolerance in mice that is not alleviated by concomitant somatostatin subtype receptor 5 knockout.
Article in Annals of surgery, 2002. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveTo examine the long-term effects of Sur KO, SSTR5 KO, and double Sur/SSTR5 KO on insulin secretion and glucose regulation. SUMMARY BACKGROUND DATA: The sulfonylurea receptor (Sur) and somatostatin receptor type 5 (SSTR5) play an integral role in the regulatory pathways of the endocrine pancreas. Sur knockout (KO) and SSTR5 KO mice were generated in the authors' laboratories and crossbred to generate Sur/SSTR5 KO mice. All mice were genotyped by Southern blotting and polymerase chain reaction analysis.
methodsOne-year-old Sur KO, Sur/SSTR5 KO, SSTR5 KO, and age-matched wild-type control mice underwent single-pass perfusion of isolated pancreata with low and high glucose concentration (n = 4-6/group). Another group of mice also underwent intraperitoneal glucose tolerance tests with 1.2 g glucose/kg body weight (n = 4/group per time point).
resultsSur1 KO and Sur/SSTR5 KO mice had profoundly decreased insulin secretion in vitro, whereas SSTR5 KO had increased insulin secretion compared with wild-type mice. Sur1 KO and Sur/SSTR5 mice had increased glucose response in vivo compared with wild-type mice. Sur1 KO and Sur/SSTR5 KO mice exhibit glucose intolerance and SSTR5 KO mice show increased insulin response in vitro.
conclusionsSur1 KO causes glucose intolerance and SSTR5 KO causes increased insulin secretion. However, Sur/SSTR5 double ablation does not alleviate the diabetic state of the Sur1 KO.
