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

Phospholipids have been considered biomarkers for diagnosing many diseases in recent years. However, the isolation and analysis of phospholipids still face many difficulties. Styrene-maleic acid (SMA) copolymer is currently considered suitable for the separation and analysis of phospholipids due to its ability to enhance and improve the solubility of phospholipid bilayers on cell membranes. In this work, metal-free atom transfer radical polymerization was first exploited to graft SMA copolymer onto the surface of silica gel. With glycerol monolaurate (GML) as the derivatization reagent, Sil-SMA-GML polymer-brush silica-based stationary phase was first developed. The chromatographic retention mechanism revealed that the Sil-SMA-GML column is of hydrophilic/reversed-phase mixed-mode retention modes. The chromatographic separation performance evaluation indicated that the Sil-SMA-GML column had excellent separation capabilities for both hydrophilic and hydrophobic compounds. The maximum column efficiency was up to 78,600 N/m. The Sil-SMA-GML column could also achieve simultaneous separation and analysis of different phospholipid classes and species as well as complex phospholipid extracts from human serum and exosomal phospholipid extracts, demonstrating the good potential of the developed stationary phase.
