Bottom-up and top-down profiling of pentosan polysulfate.
Article in The Analyst, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Pentosan polysulfate (PPS) is a semi-synthetic glycosaminoglycan (GAG) mimetic. PPS, synthesized through the chemical sulfonation of a plant-derived β-(1 → 4)-xylan, is the active pharmaceutical ingredient of the drug Elmiron™ used to treat interstitial cystitis. Unlike natural GAGs that can be enzymatically broken down into oligosaccharides for analysis, PPS is an unnatural polyanionic polysaccharide and is not amenable to such an analytical approach. Instead reactive oxygen species were used for the controlled depolymerization of PPS and the resulting oligosaccharide fragments were then analyzed by liquid chromatography-mass spectrometry (LC-MS) to obtain bottom-up information on its composition. Because PPS has an average molecular weight ranging from 4000 to 6000 Da, similar to that of low molecular weight heparin, this suggested that it might be possible to use LC-MS on its intact chains and perform top-down analysis. The bottom-up and top-down analysis of PPS provides the first detailed compositional and structural information on PPS. Finally, we examined whether PPS would interfere with polysaccharide lyases and hydrolases, used in the analysis of natural GAGs such as chondroitin sulfates, heparan sulfate, and keratan sulfates. We found that PPS did not interfere with GAG analysis, suggesting that a combination of chemical and enzymatic treatment could be used to analyze samples containing both natural GAGs and PPS.
