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
The potential hepatotoxicity of Herba Epimedii is a focal point in traditional Chinese medicine security applications. As determined in our previous study, the flavonoid constituents of Herba Epimedii, sagittatoside A, icariside I, baohuoside I and icaritin, are related to the hepatotoxicity of this herb. However, the hepatotoxic mechanism of these components needs to be clarified further, and whether these components can maintain their injury action following liver metabolism needs to be confirmed. Herein, the effects of sagittatoside A, icariside I, baohuoside I and icaritin on the apoptosis of HepG2 cells and the expression of key proteins, including Bax, Bcl-2, Caspase-3 and Caspase-9, were evaluated. Moreover, with liver microsome incubation, the influences of metabolism on the apoptotic activities of these components were investigated. Then, by HPLC-MS/MS analyses, the in vitro metabolic stability of these components was determined after incubation with different kinds of liver microsomes to explain the reason for the influence. The results suggested that sagittatoside A, baohuoside I and icaritin could induce apoptosis, which is likely to be closely related to the induction of the intrinsic apoptosis pathway. After metabolic incubation, the sagittatoside A and icaritin metabolism mixture could still induce apoptosis due to less metabolic elimination, while the icariside I and baohuoside I metabolism mixtures respectively got and lost the ability to induce apoptosis, probably due to quick metabolism and metabolic transformation. The findings of this study may provide important references to explore the material basis and mechanism of the hepatotoxicity of Herba Epimedii.
