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

Ephedrine alkaloids-free Ephedra Herb extract (EFE) was developed to reduce the adverse effects of Ephedra Herb, a constituent drug in Kampo medicines. It is produced by decocting Ephedra Herb with hot water and excluding the ephedrine alkaloids. EFE has analgesic and anti-cancer effects and inhibits respiratory viruses in vitro. To assess the pharmacological action of EFE in vivo, we evaluated its effect on the replication of murine hepatitis virus (MHV), a coronavirus that causes hepatitis, pneumonia, and severe acute respiratory syndrome-like symptoms, within infected mice. On Day 0, MHV was inoculated intranasally into female BALB/C mice, and EFE was orally administered once/day at 350-700 mg/kg (n = 10/group) starting 1 h after inoculation until Day 5. Through a plaque assay, MHV was detected on Day 5 in the lung and liver in all inoculated mice, but the titer was significantly lower in the EFE groups as compared with untreated control mice. Although not statistically significant, the clinical score for respiratory irregularity tended to be lower in the EFE treatment groups. In conclusion, EFE inhibits MHV replication in an in vivo mouse model of human coronavirus infection and exerts pharmacological action in the lung and liver.
