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

We evaluated the efficacy of a single intravenous dose peramivir for treatment of influenza B virus infection in ferrets and cynomolgus macaques in the present study. A single dose of peramivir (60 mg/kg of body weight) given to ferrets on 1 day postinfection with influenza B virus significantly reduced median area under the curve (AUC) virus titers (peramivir, 8.3 log(10) 50% tissue culture infective doses [TCID(50)s] · day/ml; control, 10.7 log(10) TCID(50)s · day/ml; P < 0.0001). Furthermore, nasal virus titers on day 2 postinfection in ferrets receiving a single injection of peramivir (30 mg/kg) and AUCs of the body temperature increase in ferrets receiving a single injection of peramivir (30 and 60 mg/kg) were lower than those in ferrets administered oral oseltamivir phosphate (30 and 60 mg/kg/day twice daily for 3 days). In macaques infected with influenza B virus, viral titers in the nasal swab fluid on days 2 and 3 postinfection and body temperature after a single injection of peramivir (30 mg/kg) were lower than those after oral administration of oseltamivir phosphate (30 mg/kg/day for 5 days). The two animal models used in the present study demonstrated that inhibition of viral replication at the early time point after infection was critical in reduction of AUCs of virus titers and interleukin-6 production, resulting in amelioration of symptoms. Our results shown in animal models suggest that the early treatment with a single intravenous injection of peramivir is clinically recommended to reduce symptoms effectively in influenza B virus infection.
