Systematic Optimization of an SLE-DAPTAD LC-MS/MS Workflow for Simultaneous Quantification of Low-Abundance Vitamin D
Article in Rapid communications in mass spectrometry : RCM, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
rationaleLiquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis of vitamin D
methodsFive sample-preparation approaches-simple protein precipitation, liquid-liquid extraction, salting-out assisted liquid-liquid extraction, solid-phase extraction, and supported liquid extraction-were evaluated under comparable conditions. Two derivatization reagents, 4-(4'-dimethylaminophenyl)-1,2,4-triazoline-3,5-dione (DAPTAD) and 2-fluoro-1-methylpyridinium-p-toluenesulfonate (FMP-TS), were compared. The selected workflow was validated according to bioanalytical method validation criteria.
resultsSupported liquid extraction using ethyl acetate/methyl tert-butyl ether (1:1, v/v) provided the best overall balance of signal intensity, reproducibility, simplicity, and suitability for high-throughput processing. DAPTAD derivatization produced a substantially higher MS response than FMP-TS and was selected for the final method. The optimized SLE-DAPTAD LC-MS/MS workflow showed good linearity (r
conclusionsThe optimized SLE-DAPTAD LC-MS/MS workflow provides a simple, sensitive, and automation-compatible approach for simultaneous quantification of four vitamin D
