1 · What the graph read from it

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.

2 · The registry

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 porcine epidemic diarrhea virus (PEDV), belonging to the α-coronavirus, is the causative agent of porcine epidemic diarrhea (PED). Presently, protection from the existing PEDV vaccine is not effective. Therefore, anti-PEDV compounds should be studied. Berbamine (BBM), Fangchinoline (FAN), and (+)-Fangchinoline (+FAN), are types of bis-benzylisoquinoline alkaloids that are extracted from natural medicinal plants. These bis-benzylisoquinoline alkaloids have various biological activities, including antiviral, anticancer, and anti-inflammatory properties. In this study, we found that BBM, FAN, and +FAN suppressed PEDV activity with a 50% inhibitory concentration of 9.00 µM, 3.54 µM, and 4.68 µM, respectively. Furthermore, these alkaloids can decrease the PEDV-N protein levels and virus titers in vitro. The time-of-addition assay results showed that these alkaloids mainly inhibit PEDV entry. We also found that the inhibitory effects of BBM, FAN, and +FAN on PEDV rely on decreasing the activity of Cathepsin L (CTSL) and Cathepsin B (CTSB) by suppressing lysosome acidification. Taken together, these results indicated that BBM, FAN, and +FAN were effective anti-PEDV natural products that prevented PEDV entry and may be considered novel antiviral drugs.
