The protective effect of a combination of human intracellular and extracellular antibodies against the highly pathogenic avian influenza H5N1 virus.

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
backgroundThe highly pathogenic avian influenza H5N1 virus poses a serious threat to humans. Due to its antiviral activity, antibody-based therapy is one of the possible effective countermeasures. Here, a combination of intracellular and extracellular human antibodies was investigated and showed an improved protective effect.
methodsThe scFv4F5-based intracellular antibody vectors and IgG1 extracellular antibody were constructed and expressed, respectively, and the sensitivity, specificity, and affinity of these antibodies were determined in vitro. In vivo, the protective effect of IgG1 and the combination of antibodies were tested respectively. Furthermore, the dynamics of viral replication, the related cytokines and apoptosis-related proteins were detected.
resultsIn vitro, the expressed intracellular antibody inhibited H5N1 virus propagation and the IgG1 exhibited high specificity, sensitivity, and affinity against the H5N1 virus. In vivo, the extracellular antibody could inhibit viral propagation in a dose-dependent manner. The protective effect of IgG1 was good in a mouse model, and the survival was 100% at a dose of 15 mg/kg under infection with 100 TCID
conclusionsThis antibody combination technique could be used as an appropriate and powerful alternative to antiviral therapy.
