The ammonia-catalyzed release of glycoprotein N-glycans.
Article in Glycoconjugate journal, 2018. 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
Despite the great significance of release and analysis of glycans from glycoproteins, the existing N-glycan release methods are undermined by some limitations and deficiencies. The traditional enzymatic protocols feature high N-glycan release specificity but are generally costly and inefficient for some types of N-glycans. The existing chemical methods require harsh reaction conditions or are accompanied by the remarkable formation of by-products. Herein, we describe a versatile chemical method for the release and analysis of N-glycans from glycoproteins. This method differs from the existing methods as only aqueous ammonia is used to catalyze the N-glycan release reactions. Optimization of reaction conditions was performed using RNase B as a model glycoprotein and the obtained results indicated a highest N-glycan yield in ammonia at 60 °C for 16 h. Comparison of this method with traditional enzymatic protocols and recently reported NaClO methods confirmed the good reliability and efficiency of the novel approach. We also successfully applied this method to some complex biological samples, such as Ginkgo seed protein, fetal bovine serum (FBS) and hen egg white, and demonstrated its great compatibility with various neutral N-glycans, core α-1,3-fucosylated N-glycans and sialylated N-glycans. This method is very simple and cost-effective, enabling convenient analysis and large-scale preparation of released reducing N-glycans from various biological samples for structural and functional glycomics studies.
