Nano-LC with New Hydrophobic Monolith Based on 9-Antracenylmethyl Methacrylate for Biomolecule Separation.
Article in International journal of molecular sciences, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
In this study, new monolithic poly(9-anthracenylmethyl methacrylate-co-trimethylolpropane trimethacrylate (TRIM) columns, referred as ANM monoliths were prepared, for the first time, and were used for the separation media for biomolecules and proteomics analysis by nano-liquid chromatography (nano-LC). Monolithic columns were prepared by in situ polymerization of 9-anthracenylmethyl methacrylate (ANM) and trimethylolpropane trimethacrylate (TRIM) in a fused silica capillary column of 100 µm ID. Polymerization solution was optimized in relation to monomer and porogenic solvent. Scanning electron microscopy (SEM) and chromatographic analyses were performed for the characterization studies of ANM monoliths. The ANM monolith produced more than 46.220 plates/m, and the chromatographic evaluation of the optimized ANM monolith was carried out using homologous alkylbenzenes (ABs) and polyaromatic hydrocarbons (PAHs), allowing both strong hydrophobic and π-π interactions. Run-to-run and column-to-column reproducibility values were found as <2.91% and 2.9-3.2%, respectively. The final monolith was used for biomolecule separation, including both three dipeptides, including Alanine-Tyrosine (Ala-Tyr), Glycine-Phenylalanine (Gly-Phe), and L-carnosine and five standard proteins, including ribonuclease A (RNase A), α-chymotrypsinogen (α-chym), lysozyme (Lys), cytochrome C (Cyt C), and myoglobin (Mb) in order to evaluate its potential. Both peptides and proteins were baseline separated using the developed ANM monolith in nano-LC. The ANM monolith was then applied to the protein and peptide profiling of MCF-7 cell line, which allowed a high-resolution analysis of peptides, providing a high peak capacity.
