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
Steroid hormones play crucial regulatory roles in human growth, development, reproduction, and the maintenance of internal environmental homeostasis. Because the concentrations of most hormones in the body are extremely low and their chemical properties vary widely, developing an accurate and sensitive quantitative method has become a primary objective in clinical diagnostics. In this study, an isotope dilution liquid chromatography-tandem mass spectrometry (ID-LC-MS/MS) method was developed and validated for the simultaneous quantification of 22 steroid hormones in human serum. To enhance extraction and purification efficiency, a protein precipitation-solid-phase extraction (PP-SPE) approach was employed, forming a "dual purification" strategy. The limits of quantification for progesterone, cortisol, dihydrotestosterone, and dehydroepiandrosterone sulfate were 0.05, 0.50, 0.05, and 1.00 ng/mL, respectively, representing an improvement over previously reported values obtained using similar sample pretreatment methods. Method validation results demonstrated strong linearity for all 22 steroid hormones (R
