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
The glycan chain of the S-layer protein of Geobacillus tepidamans GS5-97(T) consists of disaccharide repeating units composed of L-rhamnose and D-fucose, the latter being a rare constituent of prokaryotic glycoconjugates. Although biosynthesis of nucleotide-activated L-rhamnose is well established, D-fucose biosynthesis is less investigated. The conversion of alpha-D-glucose-1-phosphate into thymidine diphosphate (dTDP)-4-dehydro-6-deoxyglucose by the sequential action of RmlA (glucose-1-phosphate thymidylyltransferase) and RmlB (dTDP-glucose-4,6-dehydratase) is shared between the dTDP-D-fucose and the dTDP-L-rhamnose biosynthesis pathway. This key intermediate is processed by the dTDP-4-dehydro-6-deoxyglucose reductase Fcd to form dTDP-alpha-D-fucose. We identified the fcd gene in G. tepidamans GS5-97(T) by chromosome walking and performed functional characterization of the recombinant 308-amino acid enzyme. The in vitro activity of the enzymatic cascade (RmlB and Fcd) was monitored by high-performance liquid chromatography and the reaction product was confirmed by (1)H and (13)C nuclear magnetic resonance spectroscopy. This is the first characterization of the dTDP-alpha-D-fucopyranose biosynthesis pathway in a Gram-positive organism. fcd was identified as 1 of 20 open reading frames contained in a 17471-bp S-layer glycosylation (slg) gene cluster on the chromosome of G. tepidamans GS5-97(T). The sgtA structural gene is located immediately upstream of the slg gene cluster with an intergenic region of 247 nucleotides. By comparison of the SgtA amino acid sequence with the known glycosylation pattern of the S-layer protein SgsE of Geobacillus stearothermophilus NRS 2004/3a, two out of the proposed three glycosylation sites on SgtA could be identified by electrospray ionization quadrupole-time-of-flight mass spectrometry to be at positions Ser-792 and Thr-583.
