High-Throughput Analysis of 25-OH-Vitamin D2 and D3 Using Multichannel Liquid Chromatography-Tandem Mass Spectrometry.
Article in Methods in molecular biology (Clifton, N.J.), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Liquid-chromatography tandem mass spectrometry (LC-MS/MS) has been shown to be an effective approach in the clinical analysis of 25-OH-vitamin D in patient serum. Test volumes vary among laboratories and different levels of throughput are required for different settings. LC-MS/MS assays with multiple LC channels can be beneficial for labs with the demand of large sample volume (e.g., 300 or more samples) to control costs and fulfill a reasonable turnaround time. We hereby present an assay that employs 4 LC channels (4-plex), which are coupled to the TSQ Endura triple-quadrupole (QqQ) MS instrument, for a high-throughput solution. Briefly, the pre- and postelution segments of the LC gradient are diverted to waste via solenoid valve controls, reserving the data acquisition for only the elution segment per injection per channel at a time. The multiplexing affords a manifold increase in throughput and the optimization of the duty cycle, without compromise in assay performance and precision.
