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
objectiveTo develop a high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method for simultaneous determination of atorvastatin and voriconazole in rat plasma and investigate the pharmacokinetics of atorvastatin and the changes in voriconazole concentration in rats after administration.
methodsPlasma samples were collected from rats after intragastric administration of atorvastatin alone or in combination with voriconazole. The samples were treated with sodium acetate acidification, and atorvastatin and voriconazole in the plasma were extracted using a liquidliquid extraction method with methyl tert-butyl ether as the extractant. The extracts were then separated on a Thermo Hypersil Gold C18 (2.1×100 mm, 1.9 μm) column within 6 min with gradient elution using acetonitrile and water (containing 0.1% formic acid) as the mobile phase; mass spectrometry detection was achieved in selective reaction monitoring (SRM) mode under the positive ion scanning mode of heated electrospray ion source (H-ESI) and using transition mass of m/z 559.2→440.2 for atorvastatin and m/z 350→280 for voriconazole, with m/z370.2→252 for lansoprazole (the internal standard) as the quantitative ion.
resultsThe calibration curves were linear within the concentration range of 0.01-100 ng/mL (
conclusionsThe HPLC-MS/MS system we established in this study is simple, rapid and sensitive and allows simultaneous determination of atorvastatin and voriconazole in rat plasma. Some pharmacokinetic parameters of atorvastatin are changed in the presence of voriconazole, and their clinical significance needs further investigation.
