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

Viruses can rapidly adapt and evolve to new, unfavorable environments due to their decreased replication fidelity, large reproductive index, and short life cycle. Often, these adaptations that enable increased fitness in a new, specialized environment come with a trade-off of decreased fitness in a standard, general environment. Understanding the mechanistic basis for these fitness trade-offs has provided important insight into vaccine development, mechanism of action of antivirals, and function of viral proteins. Here, we sought to identify how a specialist murine norovirus (MNV) could be converted to a jack of all trades through a novel mutation without genetic reversion. Previously, we found that a mutation in MNV (NS6
