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

Respiratory syncytial virus (RSV) and the common commensal and opportunistic pathogen, non-typeable Haemophilus influenzae (NTHi) both serve as a frequent cause of respiratory infection in children. Although it is well established that some respiratory viruses can increase host susceptibility to secondary bacterial infections, few studies have examined how commensal bacteria could influence a secondary viral response. Here, we examined the impact of NTHi exposure on a subsequent RSV infection of human bronchial epithelial cells (16HBE14o-). Co-culture of 16HBE14o- cells with NTHi resulted in inhibition of viral gene expression following RSV infection. 16HBE14o- cells co-cultured with heat-killed NTHi failed to protect against an RSV infection, indicating that protection requires live bacteria. However, NTHi did not inhibit influenza A virus replication, indicating that NTHi-mediated protection was RSV-specific. Our data demonstrates that prior exposure to a commensal bacterium such as NTHi can elicit protection against a subsequent RSV infection.
