Comprehensive chemical analysis of polyphenols in the ethyl acetate extract from the roots of Ephedra sinica Stapf and evaluation of its therapeutic effects on SU5416/hypoxia-induced pulmonary arterial hypertension 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
Pulmonary hypertension (PH) is a deadly disease with limited treatment options and poor long-term survival, necessitating the discovery of novel therapeutics. Our previous study has revealed that dimeric proanthocyanidins (PACs) mainly existed in the ethyl acetate extract from the roots of Ephedra sinica Stapf (ERE), however, its therapeutic effects on SU5416/hypoxia-induced pulmonary hypertension (PH) rats remain elusive. In this study, column chromatography combined with UPLC-LTQ-Orbitrap-HRMS analysis was performed to comprehensively characterize polyphenols in ERE. The therapeutic effects of ERE were investigated using the SU5416/hypoxia rat model, in which the rats were injected with SU5416 (20 mg/kg), followed by a three-week hypoxia exposure (10% O
