Integrated UPLC-MS/MS and UPLC-Q-TOF-MS/MS analysis to reveal pharmacokinetics, tissue distribution, metabolism, and excretion of sipeimine in rats.

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
Background and Objective: Methods: A rapid, sensitive, and selective UPLC-MS/MS approach was developed to the quantification of sipeimine in various biological samples and successfully applied to the investigation of pharmacokinetic characteristics, tissue distribution, and excretion of sipeimine in rats. A reliable UPLC-Q-TOF-MS/MS combined with a scientific metabolite identification strategy was used to characterize the metabolic transformation of sipeimine in rat plasma and urine. Results: The established UPLC-MS/MS method was accurate and reliable with a good linearity (r Conclusion: The pharmacokinetics, tissue distribution, metabolism, and excretion of sipeimine were comprehensively characterized and elucidated. These results are expected to prove useful for the interpretation of the pharmacokinetic and pharmacodynamic characteristics of sipeimine and the traditional Chinese medicines containing sipeimine.
