A Bioanalytical Liquid Chromatography Tandem Mass Spectrometry Approach for the Quantification of a Novel Antisense Oligonucleotide Designed for Parkinson's Disease: A Rat Brain Biodistribution Study.

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
Antisense oligonucleotides (ASOs) represent a unique category of therapeutics targeting disease-related RNAs. Since this new therapeutic category emerged, the immediate need to analyze ASOs in clinically relevant biological matrices has led to several methodologies, such as ligand binding assays and imaging techniques. To overcome issues in specificity and provide exact quantitative data for ASOs, a new LC-MS/MS method was developed to analyze in brain tissue a novel 4-10-4 gapmer ASO with the potential for treating Parkinson's disease with phosphorothioated backbone and 2'-O-(2-methoxyethyl) modifications. The sample pretreatment protocol to extract the ASO from brain tissue employed solid phase extraction (SPE) and protein digestion. The LC-MS/MS method was fully optimized, validated and applied to quantify the target ASO in brain tissue samples following an
