1 · What the graph read from it

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.

2 · The registry

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

Plasma lysosphingolipids are highly elevated in patients with Gaucher, Krabbe, Fabry, and Niemann-Pick diseases and tend to accumulate to a greater extent than their respective primary sphingolipids in the plasma of affected patients. In this chapter, we describe two liquid chromatography tandem mass spectrometry (LC-MS/MS) methods to measure plasma concentrations of four lysosphingolipids species. The first method described measures glucosylsphingosine (lyso-GL1) and galactosylsphingosine (psychosine), biomarkers that accumulate in Gaucher and Krabbe diseases, respectively. The second method measures globotriaosylsphingosine (lyso-Gb3) and sphingosylphosphorylcholine (lyso-SPM), biomarkers for Fabry and Niemann-Pick diseases, respectively. Each method utilizes isotope-labeled internal standards and multipoint calibration curves to quantify the analytes of interest. Briefly, plasma samples are mixed with five volumes of LC-MS grade methanol containing internal standard, and protein is removed via centrifugation. Supernatant is dried and resuspended in initial mobile phase. Samples are separated by liquid chromatography using either a BEH amide column (lyso-GL1 + psychosine) or a C18 column (lyso-Gb3 + lyso-SPM). Protonated analytes are measured by selected reaction monitoring (SRM) in positive electrospray ionization mode. Using these methods, we have observed elevations of these lyso- species in Gaucher, Fabry, and Niemann-Pick and successfully distinguished different subtypes reflecting the disease severity.
