Early steps in glycosylphosphatidylinositol biosynthesis in Leishmania major.
Article in The Biochemical journal, 1997. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
A cell-free system based on washed Leishmania major membranes was labelled with GDP-[3H]Man in the presence of synthetic glucosaminyl-phosphatidylinositol (GlcN-PI) and N-acetylglucosaminyl-phosphatidylinositol (GlcNAc-PI). In both cases, the major radiolabelled products were Man alpha 1-4GlcN alpha 1-6myo-inositol1-HPO4- (sn-1, 2-dipalmitoylglycerol) and Man alpha 1-4GlcN alpha 1-6myo-inositol1-HPO4- (sn-1-palmitoyl-2-lyso-glycerol), to which an additional d-mannose residue was added when a chase with an excess of GDP-Man was performed. The L. major cell-free system can therefore be used to observe the actions of four enzymes, namely GlcNAc-PI de-N-acetylase, Dol-P-Man-GlcN-PI alpha 1-4-mannosyltransferase, a phospholipase A2-like activity and a second alpha-mannosyltransferase activity. The substrate specificities of the first two of these enzymes were studied using a series of substrate analogues. GlcNAc-PI de-N-acetylase was tested against a variety of N-acylated GlcN-PI substrates and was able to cleave N-acetyl and N-propyl groups but not larger groups such as N-butyl, N-isobutyl, N-pentyl and N-hexyl. The Dol-P-Man-GlcN-PI alpha1-4-mannosyltransferase activity required the amino group of the glucosamine residue and the d-configuration of the myo-inositol residue of the GlcN-PI acceptor substrate.
