A Simplified and Robust LC-MS/MS Method for Simultaneous Quantification of Six Steroid Hormones Associated With Polyendocrine Metabolic Ovarian Syndrome.
Article in Biomedical chromatography : BMC, 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
Polyendocrine metabolic ovarian syndrome (PMOS), formerly known as polycystic ovary syndrome (PCOS), is characterized by dysregulation of multiple steroid hormones. Accurate quantification of these analytes is essential for laboratory evaluation; however, currently may involve complex sample-preparation workflows or provide insufficient analytical coverage, particularly for dehydroepiandrosterone sulfate (DHEAS). A liquid chromatography-tandem mass spectrometry (LC-MS/MS) assay was established for the simultaneous measurement of six steroid hormones associated with PMOS. Sample preparation combined liquid-liquid extraction with protein precipitation. Chromatographic separation was completed within 6 min. Validation followed international recommendations and included linearity, sensitivity, precision, accuracy, matrix effects, selectivity, and specificity. All analytes showed excellent linearity (R = 0.9959-0.9995), with intra- and inter-day CVs ≤ 5.6%. Spike recovery ranged from 85.2% to 114.9%. Accuracy was further supported by third-party QC materials and successful participation in an external quality assessment program. The assay provided an expanded linear range for DHEAS (20-20,000 ng/mL). This validated LC-MS/MS assay provides rapid, sensitive, and reproducible quantification of six PCOS-related steroid hormones and is suitable for routine laboratory implementation.
